Model 510 date code help.
Re: Model 510 date code help.
The 478 is in the serial # location Rem stamped on the M/510 through 1941. Your date code might be LH. The L would mean February. The H would stand for 1939. It looks like you have a very early M/510. It was introduced in March 1939. Rem usually started production a few months before the introduction so they would have rifles on hand when the were introduced. The offset location of the serial # was done so the same stamping process could be used on barrels for the M/512 that had a magazine tube that prevent seeing the serial # if it was stamped on the bottom of the barrel.

The date code can be followed by inspector/testing/etc numbers or stamps. If there is an additional date code is followed by a 3 the gun has been returned to the factory for repair.
