My brother will be delivering an air filter to the chapter with the TRMU next week, apologies I don't recall his name
Stay in touch, we are doing a ground up on an SV2S so plenty of duplication of requirements to save $
Cheers

I can put you in touch with a guy from somerset with a very original R100, we did the same for another chap on here.
The body on his is original so measurements and pictures might prove useful
Regards
