replacement barrels for Winchester lever action rifles.|General Discussions & Questions|Forum|Winchester Collector

is there a place to purchase replacement barrels for Winchester 1892 lever action rifle in 357 magnum.  Or do I have to have one custom made? mid west gun works told me they can no longer get Winchester barrels, and there seems to be none what so ever to be had in any caliber. I have a 1914, 1892 receiver that has been converted to 357 magnum, How ever the original barrel was re chambered for 357 but not completely bored all the way out. the gun smith could not remove the barrel to finish boring it all the way out and cut the barrel off as close to the chamber as they could to avoid an accident. I purchased the parts with the intention of re barreling this receiver and having a useable rifle to keep or sell. Any help would be greatly appreciated.
