As Richard Marquise himself said: What do we know about the MST Timers? Who designed it and who built them?

The MST Timers | PT35B

Who ordered them and for what purpose. How many different types were designed and how many were built? These are some of the questions we need to answer. She stated that, according to a delivery note CPimage 1Thuring supplied 24 such circuit boards on 16 August According to a further delivery note CPimage 1Thuring supplied 34 such circuit boards on 5 November Although the Commission recognises that any assessment of the reasonableness of the verdict must proceed purely on the evidence before the trial court King; Campbell v HMA SCCRthe account given to the defence by Hinshiri is of assistance in understanding why no such challenge was made.

In his defence precognition see appendix Hinshiri confirmed that he had ordered a quantity of MST timers and that these had subsequently been delivered to him.

A similar account was given by him when questioned by the Scottish police in Libya on 30 October see appendix. A total of twenty were built by Lumpert, ten for use in a waterproof container boxed and ten which were free standing unboxed. At the time of this writing, I am not satisfied with the official story regarding the timeline of the delivery of these timers to Libya.

MST Delivery to Libya.

It is just slang for the process and does not tell anything about the material itself. In the case of these Thuring boards, it is actually a mix of Lead and Tin. Notice that the frequency on the quartz does not match the frequency on the order.

I have found the explanation to this discrepancy. Building the MST Timers. Quartz Crystal Design Note. These boxes raise an important question. Photo 1 is one of our timers although I do 44518 recognize the black electric cable. Photo 4 is a MST timer with a 2 position timing switch. I guess that Bollier did the soldering. This is a pre-series timer because the condenser has been soldered diagonally and the soldering points near the switches of the power cable have not been covered with a plastic protective sheet.

On the other hand I can verity that the circuit board has been coated with a protective lacquer which points to a later development of circuit board. Bollier often visits me in the laboratory and helps with simple technical work and I remember that in about the summer of he soldered a battery and cable onto an MST timer. Photo 7 This is an oscillator with the resistors which were added later. It must be one of the pre-series timers. The pre-series timers had protective lacquer only on one side.

We have done so when his evidence has not been challenged and appears to have been accepted, or where it is supported from some other acceptable source. We 45118, for example, that in or about July on a visit to Tripoli, Mr Bollier received a request heef electronic timers from Said Rashid or Ezzadin Hinshiri and that he had had military business dealings in relation to the Libyan Government with Ezzadin Hinshiri since the early s.

The potential order was for a large number of such timers. Mr Lumpert was told of the requirements by Mr Bollier and proceeded to develop two prototypes. There is a dispute in the evidence between Mr Bollier and Mr Meister on the one hand and Mr Lumpert on the other about the colour of the circuit boards in these prototype timers.

Mr Bollier said they were brown, Mr Meister thought 45518 were grey or brown, whereas Mr Lumpert said that they were manufactured from the green coloured circuit boards supplied by Thuring.

What we do however accept is that later in the summer of the two prototypes were delivered by Mr Bollier to the Stasi in East Berlin, whatever be the colour of their circuit boards.

This is consistent with the evidence of Mr Wenzel who at the material time was a major in the Stasi and with whom Mr Bollier then dealt. Despite this evidence we cannot, however, exclude absolutely the possibility that more than two MST timers were supplied by MEBO to ehf Stasi, although there is no positive evidence that they were, nor any reasons why they should have been.

Similarly, we cannot exclude the possibility that other MST timers may have been made by MEBO and supplied to other parties, but there is no positive evidence that they were. Equally, despite the evidence of Mr Wenzel that after the fall of the Berlin wall he had destroyed all timers supplied to the Stasi, we are unable to exclude the possibility that any MST timers in the hands of the Stasi left their possession, although there is no positive evidence that they did and in particular that they were supplied to the PFLP-GC.

No member of that organisation gave evidence but it was clear from other evidence that we heard, in particular from officers of the German police force, the BKA, that a cell of the PFLPGC was operating in what was then West Germany at least up until October The evidence which we accept showed that at least at that time the cell had both the means and the intention to manufacture bombs which could be used to destroy civil aircraft.

On 26 Octoberafter a period of surveillance, the BKA made a series of raids and arrested a number of individuals in an operation code-named Autumn Leaves. In particular they raided premises at Sandweg 28, Frankfurt and the home of Hashem Abassi in Neuss and they seized a car which had been used by Haj Hafez Kassem Dalkamoni, apparently the leader of the cell. In these premises they found radio cassette players, explosives, detonators, timers, barometric pressure devices, arms, ammunition and other items, including a number of airline timetables and seven unused Lufthansa luggage tags.

From other evidence it appeared that one of theairline timetables was a PanAm timetable. There was considerable evidence of bombs being manufactured so as to be concealed in Toshiba radio cassette players. The models being used were, however, different from the RT SF used in the PA disaster, and the timers were of a type known as ice-cube timers. These were quite different from MSTs, much less sophisticated and much less reliable, and the intention was no doubt to use them in conjunction with the barometric pressure devices to detonate the explosive.

Dalkamoni, however, was not, and he was later convicted in relation to bomb attacks on a railway line in Germany in and and possession of the weapons found at Sandweg He was sentenced to imprisonment for fifteen years.

It is possible, of course, that the cell could have re-grouped and re-stocked with the necessary materials by 21 December. There was no evidence that the cell had the materials necessary to manufacture an explosive device of the type that destroyed PA In particular there was no evidence that they had an MST timer. For the reasons given elsewhere, while a small quantity of such timers was supplied by MEBO to the East German Stasi, there is no evidence at all to suggest that any of them found their way into the hands of organisations such as the PFLP-GC.

On the evidence which we heard we are satisfied that the explosive device which destroyed PA was triggered by an MST timer alone and that neither an ice-cube timer nor any barometric device played any part in it. His instructions from them were that any bomb he made must not be primed. Moreover, while he himself did not give evidence, there was evidence of a statement given by him to FBI agents production in which he said that he never used radio cassette players with twin speakers such as the Toshiba RT-SF 16 had to convert into explosive devices.

However, given the need to finalise the review, and the fact that other grounds of referral had been identified, the decision was taken not to do so. In any event, even if an order had been obtained by the Commission under section of the Act, in terms of paragraph 6 5 of Schedule 9A it would have been open to Crown Office to notify the Commission that onward disclosure might be contrary to the interests of national security. In such circumstances, the Commission would have been bound to deal with the material in a manner appropriate for safeguarding the interests of national security.

It is therefore unlikely that the Commission would have been any less constrained in its ability to disclose the documents had it made use of its statutory powers. Our investigation is described here: MEBO used the following terms to describe the various production stages of these timers: I must now tell you about another feature of the MST Timers: This is a rather simple fact.

Yet, its consequences are not without merit. Then I call upon the Clerk of Court to read the indictment and the special defences. The first five were delivered by Bollier to Fazani in Libya in the late fall of The last ten were delivered Hijazi [2], a high ranking Intelligence officer, in Tripoli. One of their goals was to estimate the numbers of MST timers that had been built and supplied.

Contrary to what Marquise seems to believe [3], this number was not deduced from the number of Thuring boards MEBO had ordered. The upper limit of twenty timers was actually deduced from the following analysis. So with the help of Bollier, they studied this photo of the Togo timer. The reasoning is nevertheless flawed. The main board is exactly the same in both cases. This point was clearly noticed in the CIA Report.

In either case, he could not have built twenty MST timers, but only eighteen at most. But sometimes, small errors lead to a huge disaster. Come to think of it, the Lockerbie trial is a case in point. Schweizerische Isolawerke AG in Breitenbach.

The FBI report on the Togo timer does not mention the watermark on the main board of the timer. This is not surprising as the report signed by Thurman is almost a copy of the CIA report. I think that it must have been written between 26 September and 11 December This identification was added during the manufacturing process, and may offer a code to identify the source of this board.

And to the best of my knowledge, neither Dr Hayes nor Feraday ever noticed it. Solving a 30 years Old Mystery. Main board of the MST This the design of the main MST board. Here is a good quality pic of the board design: Notice the not very professional handiwork. Lumpert is shown ten photos from the DP file. His answers are reproduced under each picture.

Photo 2 is the rear side of a MST timer assembled by me. Photo 3 is a MST the circuit board without the time switch. This is a pre-series timer because the condenser has been soldered diagonally and the soldering points near the switches of the power cable have not been covered with a plastic protective sheet On the other hand I can verity that the circuit board has been coated with a protective lacquer which points to a later development of circuit board.

Photo 5 I recognize one of our timers. Photo 6 This is one of our secondary circuit boards.
