For what its worth PATM I have seen (one) 1937 that had a set of auxilliary springs and at least appeared to be factory original along with a couple other things making me think "heavy duty" or overload springs. But, over the years someone could have changed the rear end out.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
