BSA Scooters

[TTJOHN]

Hello,
I was just wondering if anyone had any experience with the manufacturing of the 250cc scooter that was produced by BSA and were badged as Sunbeam and Triumph. I would like to know who or what firm made the white  rubber grips, pedal covers and matting, also whether these are still available anywhere in the UK?
What a challenge for all you enthusiasts? :-)

Kind regards TTJohn
