What is the production date for a Remington rifle model 742 BDL serial 211464?
I found on Remington Arms website that the serial number was
made between 1951-1967 1,000-541,000
Model 742 was only made from 1960-1980 so yours would have been made between 1960 - 1967. That narrows it down a little bit for you.
According to the Remington website they began production in 1922 and ended in 1935. The serial numbers ranged from 00001 to 130425. I have the same gun with the same question but this is all I have been able to find out Remington barrels have code in alphabet which tells thf month and year of mfg the Remington society has this info
