I've just lifted this link from the 'Real Classic' forum. Wonderful stuff (well, the factory shots anyway). I'm not sure that all WD parts had the same standard of quality control).
very good where can i get a motorcycle that plays the william tell overture rather than an engine on full song i know that recording wasnt that good in those days but they are still doing it even today watch a spitfire or steam engine and some car racing the engine noise is in the back ground all you can hear is crappy music
