Hello Herb, Not having my books handy, I'd say that's a fine 1918 vintage 1911 that has been updated to 1911A1 with grips, back strap and grip safety. That being said, it needs to be broken down and identify the barrel. I didn't see a rebuild inspectors stamp on the photos you provided, so these items may have been updated at anytime by anyone. The correct barrel and misc parts will also come into play valuing it, but at first and 2nd glances I'd hazzard $750-1100, the high end being the buyer with the correct parts in his bin to restore it to as issued.
You can send it to me and Ed and we'll be glad to function test it for a few thousand rounds.
