|One more point. If you use replacement parts on a Colt you further erode the value of the gun anyway. It would no longer be a correct example, but a mixmaster. (There are no such things as "Original" Colt TSMG's, they were all examples of number 26, the Original Original!)|
That is you usual convoluted interpretation of "original" that only has cache in wanna be circles. There are prototypes and there are factory originals. The two are not in conflict with one another. Since Colt TSMG's are not Luger's with every part numerically matched, parts not original to the gun as it left the factory in 21-22 such as Remington wood, actuator, bolt, lower internals, etc, do not devalue the weapon since there is no way to prove when they were inserted into, or on, the weapon. They merely need to be originally produced parts for that make and model. Even the barrels were replaced after 1932 when TSMG's were sent back for, or delivered with, 2nd pattern Cutts.
