The bag was made from TSBD materials and the tape used made it impossible for the bag to be made elsewhere.
Roy Truly gave the FBI a sample of the paper from the book wrapping table in the 1st floor shipping department and the FBI lab examined it and compared it to the paper of the bag that was allegedly found in what was imagined to be a "Sniper's Nest"......
A report written by FBI agent Vince Drain on 11/29/63 states..... Quote: " The paper was examined by the FBI laboratory and found not to be identical with the paper gun case that was found at the scene of the shooting".....Unquote
Walt,
You know better than this. There are two reports by Drain in the National Archives. They are the same except for one saying there was a match and the other saying there wasn't a match. When asked about this, Drain said he only wrote one report and not two. It is a matter of speculation which of the two reports Drain actually wrote.
A far more interesting question, at least to me, would be; who wrote the other report (in Drain's name) and why?
The LN position is that Drain actually did write two memos and then left without knowing the results of the tests. The report reflecting the outcome of the test was the one to be used. I don't consider it a very credible explanation.
