Thanks, Tim... I'll get back to you.

I hope this is obvious, but I offer this free so someone can USE it; I ask that you don't flip it on eBAY for fun & profit. :-(

Note: my father said he thinks the tube is 21FJP22 which he installed new (converting from an old metal tube).

EDIT: THanks, folks... Tim's got dibbies. I hope it is as decent condition as I think it is.
