A good friend of mine who has a EMF reproduced the exact design thick black rubber floor mats used on EMF cars. He had a pattern shop and made the patterns himself. Exact reproductions with the fancy "Fleur de lis" designs and ribs. There is a blank area for the brake, clutch, gas pedals.
I bought 2 of them from him. I was going to use it in a rumble area of a car from 1930, but ended up selling the car. I was going to fill in the blank area with the extra one and match up the design. May work for your project ,or look good for other period RHD brass era cars.
Price is $250.00 for
