Inspiration is one thing. Speculate away. But there is no parent case for 45 acp. It was born fully formed from JMB's feverish brain.

I agree it wasn't based on another case. The .473" case head first appeared on the 1888 Commission cartridge- the 7.92x57mm(.318" j bore)- not the 7x57. I have seen a photo of the Colt prototype .41 Rimless-Smokeless pistol. It's similar to the 1905 .45 two link design. The wierd part is Winchester used the .45 ACP extractor groove for the .308 Win/7.62 NATO.
Best, Thomas.
Wouldn't you love to go back in time and interview JMB?
