A friend recently acquired a Underwood m1 carbine in excellent condition. All markings and parts ( including flash suppressor) appear to be original. The marking on the tip of thebarrell is 10-43 indicating it was made in 1943. The problem is the serial number which is E105. Yes, clear and only 3 numbers. My sources show no manufacturer beginning with and E and Underwood's serials began with 1350000 not three digits.
Any help will be appreciated.
