This car was first registered in East Sussex so the Crowborough garage badge may be the original supplier. There are clearly many aftermarket items but the dash is predominantly original. The Car Number stamp is interesting and links to Austin notation for chassis. Please add notes to images or below.

Hi Could I reproduce the dashboard dealers image on my site? https://prewardealerships.wordpress.com
Thanks
The Boorman and Son badge presumably means they sold it second-hand. This was my great grandfathers firm, Alfred Boorman and his son Kenneth. They traded from a garage generally known as Boormans Garage in Guildford Road, Woking adjacent to the Railway Hotel, and opposite the old police station. The garage closed in the early 60’s. They were Austin as well as other motor dealers. I’m not aware of another similar dealers badge. Nick Boorman
The Railway Hotel is still there, but is now the Sovereigns Pub.
