Any idea what this crank is??

saw this at a garage and junk sale. any idea what it is? this id the only pic i got.
everything there seemed to be 20's - 50's , so i am guessing this is around that old??? "fresh " in a garbage bag covered in grease.

guy had 3 model a motors, couple early flatheads outside rusting away, couple straight 6 blocks. and lots of JUNK

Thanks

 

No idea what it's from, but it kinda looks like the counter wieghts were added/welded on though.

 

not sure either but its got bobweights added by the looks of it?????

 

The weights are for inertia balancing-old school race trick. Makes it spin like a gyro >>>>.

 

Looks like a model A, reguardless it fits a 4 cylinder, not a 6 or 8.
