I’ve recently acquired this 1911 and was told it was built for the Army Marksmanship unit. It is very tight and shoots like a dream. I became interested in its history and can only make a guess about who built it and where. Just for fun I thought I’d ask the more experienced 1911 guys what they think. I’d like to know if anyone recognizes the work done to it. I would be interested to see if my research was going on the right direction. It is equipped with Bo-Mar sights. Please let me know what you think.
