Thanks for all the info. My own 3HW is a late one that should have the push button headlamp and Vokes (3HW 680??), some 1500 past the 400000 motorcycle. It seems I've a fair bit to check out. The previous owner managed to trace back its history to the first owner, who bought it crated after the war. He painted it black and rode it around Europe. It was registered in Cheltenham, Gloucester.
If you want an NOS Lycett drivers seat or an NOS Lycett Pillion seat, I have several.
In the States mate. You wouldn't happen to have a complete set of WD G3L engines cases would you?
