Ok.
I am now 99% sure this is a B52.
The Original Colour was Neon Orange and white, it wasnt a resprayed Muddyfox but it was made by the same company in the far east and shared the same production line, hence such close similarites.
Rodger was as intrigued to hear about this frame as i was to see it today.
Obviously this was a venture at the very beginning of the Uk mountain bike scene. Lester worked for Rodger and together the Tushingham Mountain bike was Born.
Rodger then continued to concentrate on the windsurfing whilst Lester formed Orange mountain bikes. (the first example being a similarly produced frame, "pathfinder/courier", sprayed in the Clockwork colours, from the same far east manufacturer.)
Myself and Maverick were fortunate enough to actually see the First example of the clockwork, being taken out of the boot of there car at the race Bitd, it was kind of nice to have this confirmed today, for years i thought i had heard wrong, or i was loosing my memory....lol)
Obviously with the Production Run of Tushingham being relatively short, before Lester leaving to form Orange Mountain bikes, original spec sheets and catalogues are scarce, but Rodger has asked me to send him a quick email as he may be able to have a route around for me, when he visits home in Yorkshire in a couple of weeks. He is sure he still has an original Spec sheet and possibly an actual colour brochure detailing the models colours and specifcations of this model and others.
Failing that he is happy to put me in contact with another ex-employee that has a couple of the original models in his own museum collection.
As and when i recieve the scans from the originals, i will forward on immediately.
I hope this has been of some help...?
