1918 Colt by Arnold Terhaar (Terhaar Gunworks) out of Jacksonville Florida. This gun was likely built in the late 50s –look at his brochure, there’s actually a five digit telephone number on it! This gun was made at a time when oversized parts did not exist. Gunsmiths had to make guns more accurate with blacksmithing and ingenuity. Custom grips made in the 40s by Walter Roper…so really Mathias Gagne.
