Tony Cordial, used to look after 'Ambasador Communications'/'Superluminal'/Team Tanglefoot' which had Bellamy surface drives, which are I think speedmaster small fitment. (will try and source a number)
Tony Toll, runs MkIII speedmasters, and has an Alladins cave of stuff, may be able to help. His company is called Aeroform, based in poole, look em up, ask for Tony 'Silverman' Toll.
And last, but not least, have you asked Tony Hamilton?
Bit odd they're all called Tony, but I promise it's a coincidence, and I'm not stalking them at all.
