If you want the cream of the collectable carbines, by all means look for a Winchester marked gun. If you're just after a good shooter, the Inland marked guns are the easiest to find and work just as well as any of the others. By the way, don't be surprised if you find a lot of carbines with WWII dated barrels, that were made by a supplier other than the maker of the reciever. It will still be the original barrel, because the govt. set up a distribution board in the middle of the war to send barrels from the makers who had excess to the makers who either didn't make barrels or who were short on them. Some of the best surplus guns I've seen in recent years were those we sent to Israel during the 1973 war over there. These were pieces that had come out our DOD reserve supplies, and were issued for defence to the farming settlments over there. You can spot them easily, because the Israelis stamped the serial numbers on the right side of the buttstock.
