I think the dimpled sound deadening material with a black bitumen like finish was first used for the 1936 range of 'streamlined' Austins. I have a Practical Motorist road test of the Austin Ten Cambridge dated 2nd January 1937 which makes a point about the sound deadening used in the bodywork. There is a photo of the drivers footwell with the carpet folded back, under which is a layer of felt. The dimpled bitumenised material is glued to the floor. I suspect if it has a bitumen finish it will stay in place and bond itself to the floor. My brother had a 1936 Ten Cambridge and the dimpled material was applied to all the body panels up to window level.
There is a type of foam carpet underlay that has a very similar dimpled finish. If this was painted underneath with bitumen I imagine it would be quite effective.
I am following this thread with interest as the Pytchley saloon will soon be on the road. This has a stressed plywood body that amplifies any noise. Rather like a motorised double bass!
