When asked if THURING had actually produced the boards he was shown in Court, Bonfadelli replied that he could not say. A few minutes later, Turnbull returned and questioned him about the watermark on the boards… I believe that this is very interesting. Let us start with the facts. An analysis will follow.
Mr. Bonfadelli, are you able to say that the two circuit boards, 431 and 432, were produced by your firm, or are you not able to say that?
A I can say that they conform to the order we had. But whether indeed they were produced in that company or not, I cannot say.
RE-EXAMINATION BY MR. TURNBULL:
Q Did the boards used by Thuring carry a watermark, Mr. Bonfadelli?
A Well, at that time we normally used the basic material of some Swiss firm, and it had a watermark. That is correct.
Q Yes. Did the watermark carried by Thuring boards have writing?
A Yes. Normally it would be the name of that company in Switzerland.
Q Do you remember what the watermark said now?
A In the watermark, it said “S” and then “I” and a “D” in capital letters.
Q And what shape was it?
A It was in an oval ring.
Q Thank you.
Question 1: Where did Turnbull learn about this “SIB watermark” and the Swiss company producing the boards for THURING AG? I have never read anything about it. Herr Bollier did not know anything about this watermark according to an email he sent me some time ago. John Ashton does not appear to know about it and he KNOWS everything that was passed to the defence team. (And more, of course!) The FBI did not request any information about it in its letter requesting assistance from Switzerland (18/10/1990) despite their request being very thorough.
Question 2: Don’t you think that it would have been a good and obvious place to start if the CIA (and later the FBI ) really wanted to trace the origin of the TOGO timer? (NB: DP/124 is the TOGO timer.) There is not a single reference to this watermark either in the CIA report nor the FBI report about K1 (the TOGO timer). And to the best of my knowledge, neither Dr Hayes nor Feraday ever noticed it. I am quite sure that Feraday’s report does not mention it.
Obviously, our goal is simple. One needs to find someone who was working for this company who can tell when (and perhaps how) they improved the adhesion of the copper to the board. To be continued.
