There should be plenty of options down there.. Check the yellow pages for welding supply...
A www may work for finding a rosebud,, but it would be nice if one of the locals could recommend a reliable source for You
The age of the torch may not matter as much as the brand.. Craftsman did not build that torch, as another manufacturer such as Forney, A O Smith or Marquette built it for Craftsman.
Without doing some research on Craftsman torches, and pictures to compare differences;; it may be easier to bring your torch into a local welding supply where these matters are dealt with more often..
Bring the entire torch in when you go.. Those Folks may recommend adding check valves or flashback arresters, and new hoses;;; if your torch needs them..
Good luck in your rosebud hunt.
The Folks at Bemidji Welding Supply have me spoiled..
Hope you can find someone as good as them
