1903's built in 1944?

[Rick the Librarian]

Remington made 03's, about 348,000 of them, till the M1903A3 was approved 21 May 1942.

Although the M1903A3 was adopted in May, 1942, it was several months until the bugs were worked out. Relatively large-scale Remington M1903A3 production didn't happen until December; the last Remington M1903 was made in March, 1943.
