Mr. Eisenberg. Were the screws used in mounting the C-250 rifle—in mounting the scope on the C-250 rifle—type of screws as those used in mounting the scope on Exhibit 139?

Mr. Frazier. Yes, sir.

Mr. Eisenberg. And the holes were the same dimensions?

Mr. Frazier. Yes, they are. And the threads in the holes are the same.

Mr. Eisenberg. Mr. Chairman, I would like C-250 admitted into evidence as Commission Exhibit 542.

The Chairman. It may be admitted.

(The article referred to was marked Commission Exhibit No. 542, and received in evidence.)

The Chairman. At this time I will interrupt to say I must now leave to attend a session of the Supreme Court, and I will return at the conclusion of the session.

In the meantime, Mr. McCloy will preside at the Commission hearing, and in the event he should be required to leave, Mr. McCloy, whatever Commissioner is here will conduct the examination in his absence.

(At this point, Chairman Warren withdrew from the hearing room.)
