you should join up and post the bike and what you've learned over at the Cabe: The Classic and Antique Bicycle Exchange - The Classic and Antique Bicycle Exchange
there'll be a lot of people interested in what you found. there's a large amount of "faked" military bikes, but if you've got absolute proof you have an amazing find.
(edit) i posted this over there for you. hope you don't mind : http://thecabe.com/vbulletin/showthr...1609#post71609
