Remington Model 600 Serial Numbers

I've come into a Remington 40-X SS 22-250 27 inch barrel woodstock rifle with the serial number 33370B. It is straight factory and on the barrel is '22-250' with the 'heart' sign and on the other side of the barrel is the REP in a circle. No other markings
It has the holes for scope blocks.
My friend ordered it when he lived in another state and he moved to this state in 1973 or close to it. He is getting rather old and can not remember the year he ordered it or what he paid for it.
I've been to the Remington site for help and I can't get an answer. All I want to know is what year was it made.
Thanks,
Dew
