These photos are of what the first of the Bs had in their footwells as far as carpet (none), rubber and vinyl covered hardboards go.
These apply to the earliest of pull handle cars. This one is an unrestored, scrupulously maintained as original #1105.
Please note that these apply with respect to the hardboard up to approx. car 2600 or so dependent on interior colour. After that they change to carpeting on the front toeboard and sides of the tunnel.
