Winchester Arms continues to exist today as a subsidiary of FN Herstal, which also owns Browning Arms. They are again much sought after firearms, particularly those manufactured for them by Miroku of Japan.
I have several Browning (A Bolt and X Bolt) rifles and if Winchester Mod.70's are made as well and from what I've read, they are, than you'd have no problem with them. A few fellas I know won't own a Browning because they are made in Japan, it's to bad because they are high quality accurate rifles.
The recent Winchesters I have handled in the local gunshops have been limited to model 70s. Quite frankly they have not been anything to write home about. The bolt operation sounds like a bad zipper, all had a sticking point roughly halfway back. These were the higher grade guns even some Super Grades. Wasn't impressed at all for the money.
I have also handled the new Marlins and would have no problem buying one as they seem to be as nice or nicer than my 1950s vintage and 1970s vintage guns.
