I have a stainless Model 70 says Classic on barrel, New Haven, in a 308 synthetic, and serial # G497xx...5 digits. Anyone know anything about this....bought sometime in the 90's but can't remember exactly when. I have the manual, box, etc. and has been shot very little. Compared to other Model 70's I have handled at some gun shows it seems as well put together as them. Anyone know anything about this model?
