A neighbour and friend back in UK had one in close to mint (restored) condition!
I sadly never managed to score a trip in it before I moved but it was a monster, and it sounded awesome when running!!!
Not many HP though for such a big engine so we've made some advances with the internal combustion engine, but sadly gone the other way with the exterior...
cant believe how slow this is progressing.....not having much time at the bench at the moment so it literally is 10 minutes here, 10 minutes there, but at least its on wheels now and i can think about those spindly looking mudguards
