The “Lads and Lassies” MEMO

A reader asks if the “Lads & Lassies” MEMO is really referring to PT/35(b)? Is the curvature of the “edge” correct?

Here is the MEMO, followed by the analysis of Feraday. I have also added the ROSE box details. [NB: CIA John Orkin claims that he suspected the Rose box as soon as he saw PT/35(b)…. He knew about these from his days in Germany. Also, keep in mind that Hinshiri and Rashid Said never asked for the timer to be set in such box.]


Here is the drawing made by Feraday.



By the way, where was Feraday on the previous day? (14/09/1989)

  1. >>> MEBO Ltd has in his camp since 1985, still 6 pieces different ROSE- housing. We will photograph the various lower bottom side of the two candidate ROSE-housing in the next few days, and publish on Facebook.

    1) The two (2 pieces) MST-13 Timer, equipped with prototype circuit boards (handmade built), which were delivered 1985, from MEBO Ltd., to the State security service (STASI) of the former GDR, were built in two light-weight plastic housing of “ROSE”. Technical Data:
    Material:: Polycarbonate, ABS, Colour: similar to RAL 7035, light grey, Ingress protection:, IP 66 to EN 60529. Temperature range: PC: -40°C to +100°C
    ABS: -40°C to +80°C.

    2) All other MST-13 Timer, delivered to Libya and to DDR, which were equipped with Thüring circuit board – were built in “ROSE” housing, which were manufactured from the following materials: Technical Data:
    Material: glass fibre reinforced polyester, Colour: similar to RAL 7000, squirrel grey, Ingress protection: IP 66 to EN 60529, Impact resistance: > 7 Joule, EN 50014, Temperature range: PUR (polyurethane) seal (std.): -40°C to +90°C
    CR (chloroprene) seal: -40°C to +100°C VMQ (silicone) seal (optional): -60°C to +130°C.

      “Now that I have seen DP 123 invoice, I see that only 12 boxes were ordered and delivered in 1985 and I conclude that only 10 housed versions were produced because two further housings went with the sample delivery in 1990.” Lumpert (SEE Lumpert Statements)

    That’s an interesting drawing of Feraday’s. I hadn’t seen it before. It certainly suggests that he believed the curvature of the edge could at least plausibly be represented as having a radius of 6.4 mm. (Personally I’m not entirely convinced the curvature actually describes a circle, but such as it does, it’s not a kick in the pants off it.)

    Bear in mind that Allen Feraday is not the sharpest knife in the drawer, by a very long way. His handling of other aspects of the forensic evidence demonstrates this quite clearly. I think my favourite is his constant promotion of his “first postulated position” for the bomb suitcase when the diagram Claiden drew and he reproduced (twice) shows quite conclusively that this position is impossible. Colin Boyd even told him it was impossible at the FAI, for a different reason (the finding of the lock of the bomb suitcase blasted into Michael Bernstein’s saddlebag thing). He sort of ummed a bit and then continued as if nothing had been pointed out to him. A corollary to that is his failure to realise that his “trial loading” packing of the duplicate bomb suitcase had the radio-cassette player in the wrong place. (The right place raises some extremely interesting questions, starting with, why would anyone pack a suitcase like that?)

    So, Feraday being a bit dim. I wouldn’t necessarily expect either perfect accuracy or perfect sense in anything he wrote. I wouldn’t expect him to get the description of PT/35b right, or even to get the radius exactly right. I still see that memo as intending to relate to PT/35b. My question is, is it the original memo sent on that date, or a re-writing? Where’s the prominent curved feature on PT/30 that could be described in that way anyway?

    Do we know the date of that drawing? Can it be verified?
