I was going to post a response to Mel’s “Birthday cartridge” thread asking about these two cartridges. But not wanting to hi-jack Mel’s great thread I decided to post a separate thread.
I recently acquired 2 different .50 Sharps cases. One is headstamped “OTTO WITT SPL” and the second “TONY SAILER 50 SH”. Any info anyone might have on them would be appreciated.
