Need replacement inner tube for my tube...

[Bigcat]

Hi All! First time postin on the tubing board. Lots of familiar names round here from the Utah board! I have an old Browning round tube that is my backup tube (the one my friends borrow that are too cheep to buy their own). It has the old style black innertube inside that is in such bad shape it can't be patched any longer. So I am hoping to get a new tube for the tube. So my question is can I buy a vinyl tube with the good easy inflate/deflate value on it and if so where.... And if not where can I get a replacement black rubber type tube with a metal valve that is bent so it doesn't jab you while sitting in the tube? I'm sure I'm not the first to need a tube replacemnt. Seems a shame to have a perfectly good tube without a tube.......

Thanks in advance!
