Manufactured from 1964 to 1972, this is one of only 1064 "kit guns" chambered in .45 ACP manufactured by Colt. These guns were produced unassembled and without sights, primarily for custom gunsmiths to produce target or competition type pistols. The .45 ACP kit guns were serial numbered from 00500-B to 01064-B, with this one being numbered "00980-B" on the right of the frame. It correctly does not bear a "VP" proof, but "T" assembler marks are present on both sides of the trigger guard. The left of the slide is marked "COLT .45 ACP/KIT" followed by the Rampant Colt and the right side of the slide has the Colt address. Most of the internal components are included in the box, many still wrapped in paper. Sights are correctly not included. Includes a kraft style box hand numbered to the gun.
