Rupp, Clone, Frankenstein, what is it.

The Rupps pretty much had the same frame from 1971 up. Hard to tell as many things are not original. Could of been Roaster, Scrambler, etc. The experts will chime in.
I do remember the 12" wheel bikes (Roadster) have a 2" longer swing arm than the 10" wheel bike. (Scrambler). Pretty sure that is the only difference. Lol. I have a good memory but it's short.
