2 major regrets in life,. marrying my first wife and selling my model 50.
had the alloy receiver,which as said,had a cracking problem with mag loads (2 .75'' mags). mine had a mod choke....best shottie i ever had.
i acquired mine in a goose pit.... had a brand new model 870.....shot 2 geese that morning,buddy got nothing.....traded straight across ,the 870 for the 50.
after the model 50, Winchester came out with the model 59....the 500miles of fiberglass barrel.(Light steel tube wrapped in 'glass.) Parts are getting VERY SCARCE...
been happy with my model 37 ITHACAS for over 40 years but would trade one plus cash in a heartbeat for another model 50...
