Does anyone know how to determine what year a 582 was manufactured by Remington? I have the serial number, and know approximately 90,000 were made between 67' and 82'.

I got mine as a kid, so I know it's mid-seventies vintage.

Also, does anyone know how to mount a scope to one of these without drilling/tapping? She's a sweety, and a darned straight shooter so I wouldn't want to bugger her up...

Feedback appreciated.
