That's funky.
Looking @ Ruttman/Bonanza pics ,, the front half of the frame looks Bonanza,, but the back looks like it's been cut & shortened,, with axel perches added to the rear outsides.
Also on the scrub brake set up,, looks like it's home made, to go thru where a jack shaft might of been ??
Looks like the front fork lower legs might of been shortened also ?
Wonder if it was a modified Shriners or circus bike or someth'n,, especially with all the added foot pegs. ????
