Just purchased my first used 1911 9mm pistol at Cabela's. Engraved on the left side of the slide barrel: AUTO-ORDNANCE CORP. then directly underneath 9MM AUTOMATIC and then to the left is a bullet shapped outline with the name Thompson engraved inside. On the right side: ESSEX ARMS then directly underneath HARDWICK, VT then directly underneath the engraved number 76521 (s/n per cabela's). They could not give me any info on the gun....date manufactured, shot xx times, etc. If anyone can help..please let me know. From what I have seen in lots of pictures on various websites...it appears there have been modifications....grips, trigger, etc. None of the pics match mine. I've attached pics of mine. Anyone have any ideal how old my 1911 is, etc ? Any info would be appreciated.
