Hi there boatyardgirl,
Congrats on getting a new project. Good luck as you tackle it.
I thought I'd give you a possibility of a brand for it.
It isn't an "Avion" as those have always been aircraft style and
construction. [Similar to Airstreams.] Not canned ham style as
far as I can find out.
There was a canned ham style brand in the 1960s [And maybe
into the 1970s.] called "Avalon." Your 'new' TT is most likely that
brand. If you pronounce both names fast they sound closely alike.
That's probably how it got registered as an "Avion".
Maybe the RVMH Hall of fame would have some info on "Avalon" TTs.

Have fun and good luck with the rebuild.
