Bulleid coach ?

[Dancess]

Attached are pictures of a coach that I bought at a swapmeet 25+ years ago, after doing a bit of research I think it is a 59ft Bulleid Brake 3rd to diagram 2121. Does anyone know the manufacturer of the brass sides and if others were / are still available?
There is still work to do to the underframe and fitting correct bogies from the NGS.

Thanks for any replies.

BHE do the 59' and the later 64'6" Bulleids; the later ones can form a Bournemouth 6 car dining set
