Few years back I picked up a used model 70 and I'd like to know which particular model it is. Only descriptions on the gun itself are "Winchester Trademark" on the right side of the bolt, "Winchester Model 70 30-06 Sprg, Made in New Haven CT USA" not quite half way down the barrel and the serial number G2273XXX. It has a synthetic stock, blind, 4 round magazine and the 3 position safety. Any info would be nice, thanks.
