Mr. Frazier. I could not say—I could not answer that specifically. However, they appear to be the same type of screw as is present on the rest of the mount—although they are somewhat larger in size than the remaining hole which is present in the lower portion of the mount.

Mr. Eisenberg. Now, I now hand you a rifle which is marked C-250. Are you familiar with this rifle?

Mr. Frazier. Yes, sir.

Mr. Eisenberg. Can you describe it briefly?

Mr. Frazier. It is an identical rifle physically to the rifle Commission's Exhibit 139, in that it is the same caliber, 6.5-mm. Mannlicher-Carcano Italian Military rifle, Model 91/38.

Mr. Eisenberg. Did you attempt to determine by use of this rifle whether the scope was mounted on Exhibit 139 by the firm which is thought to have sold Exhibit 139?

Mr. Frazier. Would you repeat that, please?

Mr. Eisenberg. Yes.

Did you make an attempt to determine, by use of this C-250, whether the firm which had sold Exhibit 139 had mounted the scope on Exhibit 139?

Mr. Frazier. Yes, sir.
