The only componant that is Winchester is the action. Can’t tell definatively with your images not clear but possibly one of the repro’s maybe .
try the 22 forum or "rimfirecentral" winchester 52 forum
It is my understanding that the 52 E was made from 1975-1980 with 652 being made. They all were single shot with a heavy 28 inch barrel ( .882" at muzzle). They were available in three different style target stocks. The pictured "sporter" is not a factory offering. It may be a great shooter, but much of its resale value is lost with the addition of that stock. Good shooting....James
