1929 Ford Station Wagon in need of seats

[36 conv sedan]

Hi guys! I am about to purchase a 1929 Woody, a 4 door station wagon, which is basically a very good older restoration, but for some reason I don't understand (and neither does the son of the owner) there is no rear seats for it, only the front one. I am not sure but I don't believe there is any rails or anything for the rear seats either.

Questions:

Are those seats a wooden structure covered with plastic as in the front seat?

Is anybody reproducing them or are there any drawings one could use to replicate them?

Thanks,
Victor
