I bought a old 1911 and have several questions that I'm hoping someone out there can answer for me. On the right side of the slide it says MODEL OF 1911.U.S. ARMY. On the right side of the frame it says No 1930XX. On the left isde of the slide it says PATENTED APR.20.1897 SEPT 9. 1902 DEC.19.1905 FEB14.1911.AUG 19.1913 COLT'S PT. FA. MFG CO. HARTSFORD. CT. U.S.A. then at the very rear of the slide it has the horse symbol. On the left side of the frame it says UNITED STATES PROPERTY AA GHS IN A CIRCLE. In the area where the hammer hits the firing pin there is a H and if you open the slide all the way on top of the frame are the letters H D and S. The pistol has been parkerized at some point. I was told by the seller that the gun was made in 1917 and was arsenal refinished at the Augusta Arsenal (hince the AA stamp). He also told me that the GHS and H stamps are inspector stamps and that the D found on top of the frame indicates it was a Gov't contract piece. What does the S mean? The gun is in excellent condition. What is a fair price for me to offer for this piece. Oh also the barrel is stamped HS which I was told meant High Standard. ANY INFO. GREATLY APPRECIATED. TIA-FIB
