Back when I was in the Navy, I was on the ASROC security force and we carried 45's. If I remember correctly we had a couple of them that had 'Singer" on the slide. There were a couple of other 45's that had another name that seemed odd but I don't remember what it was.
Did Singer make 45's back in the dark ages?
"A strong body makes the mind strong. As to the species of exercises, I advise the gun. While this gives moderate exercise to the body, it gives boldness, enterprise and independence to the mind. Games played with the ball, and others of that nature, are too violent for the body and stamp no character on the mind. Let your gun therefore be your constant companion of your walks." --Thomas Jefferson, letter to Peter Carr, 1785
