For those most likely when the ship from japan docks at the west coast.
Try arts gun shop for any browning item or service.
It going to be more cash than Numrich so try brownwells or others which will be cheaper but arts will have it. He is the man man on the brownings.
Nothing wiht numrich is ever predictable. Just because an item is in-stock is no gaurantee that they actually WANT to carry it, and something being out of stock is no indicator that they'll ever get one back in stock.
if you're hung up on getting it from them, check it weekly.
Try Sarco, like I stated in your other thread I'd get a current issue of the Shotgunnews and leaf through it. You can pick one up at most news stands, Wal-mart usually carries them too.
Numerich mostly gets their parts from guns people sell them. Usually broken or junked guns. They do get parts from suppliers but most older guns are parts guns/junk guns they bought.
