Fresh air hose

["Peter C." <nosimport@mailbag.com>]

Listers,
        Is there currently a good-looking fresh air hose for the early cars? I
remember getting one from "what doesn't grow on a rolling stone" and it was
paper covered foil. I'm asking because I think I saw a very acceptable
replacement. If they are not readily available, I'll need to know length,
diameter (4" I think) and spacing of the wire spirals. As I said, I think I
found a ready, tho obscure source, just need details.
Thanks guys.    Peter C
