Hiawatha bike -- no front badge??

[Hitman44]

is there any other ways to tell what year this is?

There should be a serial number on it. Probably on the bottom bracket or on the back of the chainstay. Cool old bike you found man.

I'd guess 55-57 from that pic. -Adam

I still can't find a number anyplace else. It is frustrating.
