Has anyone ever seen a US Ordnance marked Colt Detective Special? This one has the square butt, dates to 1940 and has the flaming ordance bomb on the top of the left side of the frame. It has also been parkerized (probably a long time ago). Standard wood grips with Colt Medallion. I know the army purchased some of these in limited numbers in WWII before the 2''Commando's came out. Any info. helpful.
