Call Pine City Gun & Pawn up in Jackson, AL... He has an old busted up Norinco that he's parting out and rebuilding. I told him I'd take the tube cover, but you're welcomed to it and I can do that deal and get it to you or he can send it to you via FedEx (that's me) or U.S. Mail. Tell him Hoss said to call and ask. You'll either be talking to Shane or Mike, but Mike goes by "Elwood" for some reason.. They're good guys to deal with and they're fun too!
My tube cover is plastic and I was going to put a wood one on it, but it's no biggy. Mine will just be a hog killer and doesn't need to be pretty.
