It is one of the few that the factory allowed to be sold to an employee. This gent was a Design Engineer. He worked primarily in the design of machine guns during Vietnam. He holds a few patents with Colt. On the side he and his partner built up this gun in the modeling department. It is the only one that I know of that has a ribbed barrel. It also has a highly beveled top strap to contour to the barrel rib. The grips were a prototype they experimented with in a plasticized wood. Forward of the trigger guard is square instead of the usual Colt oval or round. The basepin latch release has a rampant colt on the right side engraved. Your looking at the old Colt style case hardening....and on and on... :mrgreen:
I picked up the gun from the gent that retired from Colt in 1971. He and I have traded numerous emails since. He is a known design engineer as is his partner that was a master machinist. The two gents created the gun. To them, this was simply an exercise in fun. Typical of them as they prototyped a machine gun and assigned a number beginning with 007 at about the same time :mrgreen: The gent I aquired the gun from is quite interesting as are some of his aquaintances. Only fellow that I know that was friendly with Eugene Stoner.
At any rate, an interesting example of what Colt could have used to compete with Bill Rugers Single Six....
Given the choice, I think I might have bought the Colt....
I'm surprised nobody noticed the gun was fitted with a Colt Eliason rear sight..... from a 1911
