Glad someone knew the answer. Mine has the round knob but the 38's I've seen restored had a pedal similiar to the one in Jim Carters catalog for later models. I hadn't seen anywhere it seemed to attach to floor. Maybe folks didn't realize there was no pedal originally. MY33 on the 38 there is a grommet in the metal floor where the accelorator rod comes thru then the knob screws on the end of rod. Does your 33 have the wooden floor?
