The Colt was shipped before Remington Rand even got into production. Colt sent barrels to Remington Rand to help them get started as High Standard couldn't furnish the barrels to Remington Rand for their first production runs.The crummy pics make it look like a re-Park, but it isn't. Did some early Colts have a HS barrel?
When he quotes information from Clawson that is simply wrong, he is the one doing the misleading. There is no confusion in Clawson's book as to when Colt discontinued the practice of serial numbering the slides to the receiver, and he is using misinformation for his own benefit. Clawson shows which grips are correct, and he shows which barrels are correct, so being mislead is not an excuse there. Since he goes to great length to explain the slide issue, I believe he knows exactly what he is doing.Anyway, he is a nice guy as I've talked with him on the phone, however he is seriously mislead on a number of issues. If someone were to point out the fact that RR wasn't even in the .45 business when this pistol was (frame anyway) made, he might just see the light.
