There's a pair of his 1911's at the Texas Ranger museum at Waco Texas.
Those guns are profusely engraved and inlaid with gold and gems, AND are Fitz Specials... The trigger guards are cut away.
These are genuine Fitz guns since he ordered them direct from Colt.
As I recall, these were commercial 1911's not 1911-A1 models.
I have some pictures somewhere, but I took them with a film camera and I can't post them.
