NPM Carbine with 2 Odd Parts

[DaveHH]

My 5.6 Win has exactly one non Win part, a recoil plate from Underwood. Brian Q. advised that sometimes a single misplaced part is the best evidence of an original carbine. If the gun was "restored" why would the guy leave in an obvious wrong part? Especially a common cheap part? I would also look closely at the part and the stock. If original to the gun, the part will have a definite and obvious etching in the wood under the part. Leaving the fingerprint of the odd part in the wood. My Win was very difficult to remove the recoil plate and there was a very obvious and unique fingerprint in the wood. It was easy to match the two parts.
