A leather jacket is a coat made of real or imitation leather. It was a light-weight design with a unit body made of wood and imitation leather. The Smoking Room was equipped with low-backed seats of imitation leather. The re-titled series was bound in brown Kivar, or a similar imitation leather binding material. Pants are sometimes held up with string, hemp, or vegan-friendly imitation leather. Wagons were trimmed as before except imitation leather was only used on standard wagons. Early saddles were brown imitation leather but in 1954 the colour was changed to green. Standard station wagons had imitation leather upholstery while Deluxe types had genuine leather cushions.
