I had a 1915 Colt 1911 that had the US Property and 1911 U.S. Army markings horribly defaced at some point. Basically gouged out with a file. Since it was a 10% finish pistol with the only replacement part being a WWII barrel, I opted for a Turnbull restoration for a client who just wanted a pristine example and was on board for the cost of restoration. Turnbulls did a lovely job.
