You can tell that, because each chamber has been stamped with the Birmingham proofmark, indicating that each chamber in the cylinder has been proofed.
Mr. Eisenberg. Mr. Cunningham, could you explain to us the difference between a .38 S&W and a .38 Special?
Mr. Cunningham. They are completely different cartridges. One cartridge is a .38 Special, and the other cartridge is a .38 S&W, or actually written out it would be Smith and Wesson. It was developed for their weapons, and it 1s quite an old cartridge, and it is known—usually as appears on a box of ammunition—as merely a .38 S&W. However, there are many differences in the cartridges.
Mr. Eisenberg. Have you brought two—an example of each type of cartridge with you?
Mr. Cunningham. I have. First of all, this is actually a Western .38 S&W cartridge. You will see the head stamping on the base of this cartridge signifies it to be a .38 S&W.
Mr. Eisenberg. Before you go any further—Mr. Chairman, may I have this marked as an exhibit—this specimen?
I am holding a cartridge marked Western .38 S&W, and it is submitted as Commission Exhibit 587.
The Chairman. It may be admitted.
(The article referred to was marked Commission Exhibit No. 587, and received in evidence.)
Mr. Cunningham. If you would care to see one broken down, I have one with me. That is the same cartridge where the bullet has been pulled and the powder has been dumped out.
