Here is a good quality pic of the board design: In his defence precognition see appendix Hinshiri confirmed that he had ordered a quantity of MST yef and that these had subsequently been delivered to him.

Contrary to what Marquise seems to believe [3], this number was not deduced from the number of Thuring boards MEBO had ordered. 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.

She stated that, according to a delivery note CPimage 1Thuring supplied 24 such circuit boards on 16 August 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 45518 of the cell.

The reasoning is nevertheless flawed. Notice that the frequency on the quartz does not match the frequency on the order. 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, ammunition and other items, including a number of airline timetables and seven unused Lufthansa luggage tags.


In either case, he could not have built twenty MST timers, but only eighteen at most. Despite this evidence we hfe, however, exclude absolutely the possibility that more than two MST timers were supplied by MEBO to the Stasi, although there is no positive evidence that they were, nor any reasons why they should have been. Sorry, your blog cannot share posts by email. 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.

Notice the not very professional handiwork.

The MST-13 Timers

In particular there he no evidence that they had an MST timer. Photo 7 This is an oscillator with the resistors which were added later.

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.

Main board of the MST This is not surprising as the report signed by Thurman is almost a copy of the CIA report. I have found the explanation to this discrepancy. On the evidence which we heard we are satisfied that the explosive device 418 destroyed PA was triggered by an Heg timer alone and that neither an ice-cube timer nor any barometric device played any part in it. Solving a 30 years Old Mystery. 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.

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. Photo 5 I recognize one of our timers.


These are some of the questions we need to answer. But sometimes, small errors lead to a huge disaster. And to the best of my knowledge, neither Dr Hayes nor Feraday ever noticed it. Photo 3 is a MST the circuit board without the time switch.

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.

I guess that Bollier did the soldering. Photo 8 an oscillator crystal. A total het twenty were built by Lumpert, ten for use in a waterproof container boxed and ten which were free standing unboxed. 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.

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.

MEBO used the following terms to hhef the various production stages of these timers:
