When I originally made the comment, I was only referring to parts which have been intentionally numbered to match. I also collect Carbines and Garands. Swapping parts on these guns to make them more original is not an issue for me, since the historical context of the guns allowed for this and there were no specifically numbered parts to mate together. Values in the Garand and Carbine world are also not widly affected should a part from another manufacturer or production period turn up in the gun. It is expected.
Lugers, on the other hand, lend themselves much more to fraud given the large disparity in value due to all the major parts having been numbered at the factory.
I completely support restoring originality of any number of guns, but stop short at having a part number modernly applied to boost value.
This is tantamount to finding a gas trap serialed Garand and fitting it out with fake gas trap parts to pass it off as such.
