The supply of about twenty MST-13 timers to Libya is no disputed and was not challenged during the trial. Here is an extract from the SCCRC report.
The Commission notes that no documentary evidence was led at trial that directly vouched Mr Bollier’s evidence about the supply of MST-13 timers to Libya (although Mr Meister understood that Mr Bollier had personally delivered these in 1985: 22/3741).
Accordingly, it seems that the court was prepared to accept Mr Bollier’s evidence on this issue on the basis that it had not been challenged and appeared to have been accepted by the defence.
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 1998 SCCR 214), the 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-13 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 1999 (see appendix). [SCCRC REPORT 20.29]
Working their way through various interviews of MEBO people and after reviewing factual evidence such as the invoices, the investigators have been able to reconstruct the following timeline.
(Richard Marquise gives a description  of the supply of the 20 MST-13 timers to Libya. The “Fuhl Report” (BKA) gives a good summary of the timers produced. And this timeline of the various invoices provides a good check of this information.)
MEBO used the following terms to describe the various production stages of these timers: prototypes, pre-series and production-series. (Bollier had hope that he would sell thousands of them to Libya.)
Two prototypes were built in early 1985. Two quartz crystals NMP-160 (16 MHz) were ordered on 3 May 1985. These were delivered by Bollier to the STASI in mid-June 1985.
The circuit tracks of these two prototypes were not covered with “Tin”. Therefore, they cannot play a direct role in our story since both PT/35(b) and the board of the Togo timer are covered with pure Tin and a mix of Lead/Tin (like ALL boards manufactured by Thuring) respectively.
The first five MST-13 timers have a circuit board with “solder mask” on one side only and were built into boxes.
“The first five were delivered by Bollier to Fazani* (Said Rashid) in Libya in the late fall of 1985.” [Marquise]
The second five MST-13 timers have a circuit board with “solder mask” on both sides and were built without boxes.
“The second five were delivered by Bollier to an individual at the Libyan people’s Bureau in East Berlin around November 1985.” [Marquise]
The last ten MST-13 timers have a circuit board with “solder mask” on both sides and were built into boxes.
“The last ten were delivered Hijazi*(Ezzedin el Hinshiri), a high-ranking Intelligence officer, in Tripoli [in late 1985].” [Marquise]
A few comments
1) This description should not be taken too seriously. Some minor mistakes may be expected.
For instance, I have only seen one invoice for the boxes. Bollier ordered 12 ROSE boxes on 30 July 1985. Obviously, not enough to build 15 boxed MST-13 timers.
2) The Togo timer is lacquered on both sides and its corners were not cut. Therefore it can ONLY be one of the five unboxed timers of the Production-Series. In other words, it is built upon a Thuring board that was part of the second order. These boards were delivered on 12 November 1985. The logic is unescapable.
Last but not least, PT/35(b) can NOT come from any of these boards since it is covered with pure Tin and all Thuring boards are covered with a mix of Lead/Tin.
