NPM M1 Carbine date of birth

[shotgunjoel]

What is the date of birth for a National Postal Meter M1 carbine serial number 43857xx. I just picked it up at the CMP South Store. The one chart that I did find stopped before my number. Thanks for the help.

You need to find a copy of War Baby. Your sn falls in a assigned block given to NPM. In 38 months of wartime production, over 6 mil carbines were made.
