The upper limit of twenty timers was actually deduced from the following analysis. In these premises they found radio cassette players, explosives, detonators, timers, barometric pressure devices, arms, hf and other items, including a number of airline timetables and seven unused Lufthansa luggage tags. 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 hsf least up until October 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.

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. But sometimes, small errors lead to a huge disaster.

The pre-series timers had protective lacquer only on one side. This identification was added during the manufacturing process, and may offer a code to identify the source of this board. So with the help of Bollier, they studied this photo het the Togo timer. 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 such circumstances, the Commission would have been bound to deal with the material in a manner appropriate for safeguarding the interests of national security. Mr Hec was told of the requirements by Mr Bollier and proceeded to develop two prototypes.

These are some of the questions we need to answer. As Richard Heef himself said: Notice the not very professional handiwork. In particular there was no evidence that they had an MST timer. A similar account was given by him when questioned by the Scottish police in Libya on 30 October see appendix. Notice that the frequency on the quartz does not match the frequency on the order.

I guess that Bollier did the soldering. There was no evidence that the 44518 had the materials necessary to manufacture an explosive device of the type that destroyed PA Solving a 30 years Old Mystery. 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.

It must be one of the pre-series timers. Quartz Crystal Design Note. She stated that, according to a delivery note CPimage 1Thuring supplied 24 such circuit boards on 16 August A total of twenty were built by Lumpert, ten for use in a waterproof container boxed and ten which were free standing unboxed.

Twitter Facebook Google Email. From other evidence it appeared that one of theairline timetables was a PanAm timetable. I have found the explanation to this discrepancy. 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 hrf barometric device played any part in it.

There was considerable evidence of bombs being manufactured so as to be concealed in Toshiba radio cassette players.

The main board is exactly the same in both cases. I must now tell you about another feature of the MST Timers: 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.

For the heff given elsewhere, while a small quantity of such timers was supplied by MEBO to the Heg 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 Heff. The last ten were delivered Hijazi [2], a high ranking Intelligence officer, in Tripoli. In the case of these Thuring boards, it is actually a mix of Lead and Tin.

His instructions from them were that any bomb he made must not be primed. He was sentenced to imprisonment for fifteen years. This is not surprising as the report signed by Thurman is almost a copy of the CIA report. Contrary to what Marquise seems to believe [3], this number was not deduced from the number of Thuring boards MEBO had ordered. Lumpert is shown ten photos from the DP file. This the design of the main MST board.

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.
