NRA marked Colt on GB

I sent an email to the gentleman in regards to this NRA marked "Colt" and tried to explain why it wasn't correct but had no luck in convincing him. Has anyone else had any dealings with this individual? I was told to keep my opinions to myself and to go away!

I believe the same seller recently had another piece for sale that was in the same league as the one shown.
The receiver of his N.R.A. pistol is a Remington-UMC rather than a Colt.

With a few simple tools its amazing all the rare pistols you can come up with.
