Interesting to see (or imagine) the reactions of different collectors.
Parker - Spend a ton of money to restore it to showroom appearance and it will be worth a ton and a half of money.
M1 Garand - Army Ordnance repaired it, find a part no 49-85769 so it will be "correct."
USGI 1911 - Don't dare pretty it up and certainly don't shoot it.
S&W Heavy Duty - Send it to Hamilton Bowen and have it rebored to .38-40.
