NPM recoil plate question

[SloopJohnB]

I just picked up a very nice 4.3 mil NPM that is all correct, if not possibly original except for one anomaly. The recoil plate is a machined type 3, with the marking "WJ" on the bottom. I can't find a reference to that code, and am woncering if someone out there has seen it before. It appears to be the same as every other USGI type 3 I've seen, but I'm at a loss to explain/understand that marking.
I would really appreciate any assistance/info you carbine collectors can provide.
Thanks in advance,
John

I believe that part is Wadsworth Watch Case Co. for Jamestown Lounge. I know of no records that show those parts being used by NPM, but they did get subcontracted reciol plates from a couple of other makers like Lyman, so it might be original.

Thanks jimb. Another forum member indicated that these recoil plate were installed on replacement stocks. Jamestown Lounge would seem a logical supplier.

Yes they had a contract to make replacement stocks mid to late war. The type 3 plates were required to go along with the stock.

I have a NPM carbine in the 4,24 million serial range with a undated IBM barrel, the recoil plate is LN. Would the IBM barrel be correct ?

I'm thinking it's probably correct since NPM used IBM barrels, among others, from the government free issue program. Mine is serial #435xxx with an unmarked IBM barrel. Does yours have a Union Switch & Signal "U" marked receiver?

[RCS]

No there is not any U stamp on the receiver

Your serial number dates to about March 1944 and at that time NPM was using IBM barrels so it's most likely the original barrel.
