I picked up a Winchester 770 at an estate sale and I’m having a hard time finding information on it. I work nights so Winchester has been closed every time I’m awake and remember to call. All the info I could find online is that it’s an economy version of a model 70 produced from 1969-1972, and it doesn’t have a floor plate. Anyone know the difference between the 770 and the 70 other than the floor plate? I attached some pictures below, thanks!
