Can anyone please tell me roughly what year a .22LR Model 17-3, SN 8K15xx was manufactured? Thanks in advance.

Looks like 1975, if I'm squinting at the book correctly.

1975. 8K1 to 8K20763 were issued in 1975. That spread includes yours.

Thanks very much gentlemen. Pictures will be forthcoming once Big Brother finally lets me get it out of gun jail.
