Are the two front seats on my March 1931 Victoria
The rear cushion & backrest and front backrests were always the same regardless of if you had a late or early Vicky. The only difference was in the front cushions. The early used a flat bottomed cushion and the piece of wood that was under them were solid. The later cushions had a dropped center at the bottom of the seat spring. The wood that it attached to was a frame with a hollow center so that the drop center of the seat spring would set inside the wood frame.
