12/29/20 - This is a National Postal Meter M1 Carbine from early in 1944. It has correct NPM parts throughout, but the receiver was re-parkerized. Stock is marked Trimble TN in sling well with NPM inspectors cartouche on the right side, over FJA inspectors mark. Barrel is IBM, which can be correct. Terrific bore. Some notable finish loss on the barrel.
