Thought you may enjoy this rarity:
Colt 1911 that was part of the Colt-British RAF Contract of 1918 with British and RAF proof marks
Originally chambered in .455 , this is one of the very few pistols that made its way back to Colt after the end of WW1
Colt converted it from .455 to .45 acp with addition of a 45 acp barrel and overstamped the 455 with 45 acp
Copy of the Colt Letter is also pictured
Please notice that there is NO US Property stamping or military Inspectors proof marks..shipped directly form Colt's to England



* Note caliber overstamp...455 still visible underneath the 45 overstamp:

Where did the information come from that it was returned to Colt for conversion to .45 ACP? This was a common conversion by the seller for the pistols imported back into the U.S. to make then salable.

That is what I was told by several advanced collectors that most probably Colt performed the conversion to 45 acp
That of course is not Gospel without documentation...I appreciate you shedding additional light on the conversion possibility. Many Thanks
