Highly unlikely.
Your winchester model 70 which was made in 1966,was made at winchester main gun factory in New Haven,Conn.
yes
Yes the stock on a Winchester Model 12 16 gauge is the same as a 20 gauge. 16 gauge,20 gauge, and 28 gauge are all the same for the Winchester Model 12. Thanks, Tim
Aftermarket YES. Factory from Winchester NO!
You will have to call the factory to find out.
Winchester was very accommodating to their customers, so it would be possible for a model 94 to come factory equipped with a peep sight. But it would have had to be special order, standard 94's came with open, buckhorn type sights.
Your winchester model 1894 rifle was one of the first 500 rifles to leave the winchester factory in 1939.
Only the factory knows and they are not telling.
Best left to a factory trained gunsmith.
Yes,these rifles were blued at the factory at the time of production.
