Does anyone have an opinion on non FA upper marked only with the VP in a triangle? Large front hole, no deflector, sight has pressed numbers with no indent in the pin and the magazine well is a perfect fit. The only thing I have found to be a close match is probably an upper off a 1964 SP1. I purchased this used some 8-10 years ago and have always wondered if it was aftermarket Colt.
