Tippett location just round the corner from me, with the original Honda importers location within about 2 miles from there. Often pass both historic sites travelling locally. A couple of hundred metres from Tippetts is the John Cooper racing factory, in which the world of single seater racing was changed in direction to rear engined cars. Jack Brabham also near there, but a couple of miles in opposite direction, the connection too with Colin Sealey managing Brabham F1 team for a while, and building a few Honda engined bikes
