I read Model 70 on the barrel, not 70A. Does this have a hinged floor plate? What style Safety does it have? I have seen model 770 or 670 with various Safeties and Blind Magazines vs Hinged floorplates. They were marked on the barrel with the proper designation; the receivers had no marking other than Winchester. The various Scope Base manufacturers used to Designate the 1946 or 1947 smooth rear bridge (same as post 64) as 70A with the PreWar slotted rear bridge mounts as 70.
