Photograph No. 8 is an inscription "PG" on the top of the bolt of the weapon. This inscription—I do not know of my own knowledge what that is—but it could be the mark of a manufacturer or a proof mark or an inspector's mark made at the time the handle was made to be welded to the bolt.
Photograph No. 9 was taken of the bottom of the receiver of the weapon, with the stock removed. It shows the Number "40," which could refer again to the year of manufacture, 1940, on the receiver, and at the rear of the photograph a small lettered inscription referring again to an inspector stamp, a proof stamp, of some nature. The identity of this, I do not know.
Mr. Eisenberg. Mr. Chairman, I ask that these photographs be admitted as a group under the number 541.
The Chairman. You are going to put all of them in under one number?
Mr. Eisenberg. Yes. They have the subnumbers on the back, which will differentiate them.
The Chairman. They will be admitted.
(The documents referred to were marked Commission Exhibit No. 541, and received in evidence.)
Mr. Eisenberg. Can you explain why someone might call Exhibit 139 a German-made Mauser rifle or a Mauser bolt-action rifle?
Mr. Frazier. The Mauser was one of the earliest, if not the earliest, and the basic bolt-action rifle, from which many others were copied. And since this uses the same type of bolt system, it may have been referred to as a Mauser for that reason.
Mr. Eisenberg. Does this weapon show—how much use does this weapon show?
