The front seats in the early 190A Victoria (before April 1931) and the 400A Convertible Sedan had a slightly different size for the driver (1.5" wider) vs the passenger. The 180A Deluxe Phaeton has the same seat frame as that of the wider 190A & 400A seat frame.
Thanks. The weird thing is that the original seats of this car had the cups like the tudor, and we are sure these are the original seats. It is one of the first off the line (June 1930) do it is very early and perhaps they made a change?
