classic motorcycle forum

Can't help with your price Rex. Got no idea of UK values but I suspect I'd be very much tempted to buy if I lived there.
You'll be amused to know I've blown your photos up and had as good a nosy as I can and the engine is as I suspected. A Super Sport top end on a Mk12C  bottom end. I could just see the initial G of the Mk12C engine number hiding behind the carbie float bowl. It's a well known way of building yourself a Super Sport nowadays. I also saw the bike has no twistgrip but a two lever Villiers throttle fitted. Top lever to raise and lower the needle for starting and best running and the lower as the normal throttle. This is by far the best riding set up for a pre war Villiers as it allows you to give hand signals and to change gear without the engine shutting off as you do it. You learn to execute a fast hand change before the engine can over rev with this set up. Also encourages you to change at exactly the right moment.
Finally it allows you time to give a relaxed and obvious hand signal as you bowl up to an intersection. (Not that everyone understands them nowadays.)
Why anyone would want to trade in such a cutie for an Enfield is beyond me but then again I'm always surprised at how many can't change their riding style to get the best out of early bikes. Maybe he's one of them.
I'd like to know the end of the story.

They do indeed have an excellent forum: http://www.jampot.com/forum/. The club is very good.

A couple of other useful links: http://www.amcclassicspares.com/ have huge quantities of used spares; Christian's archive at http://archives.jampot.dk/ has all the manuals etc you could ever need.

Join the Owners Club.......very likely they are remanufacturing hard to find items,and certainly will know where to find stuff.Im pretty sure they have a forum,where you could ask ,even if not a member of the club........which you should be.

Thats very true Rex, I  had an interest in french bikes of the 1930s for quite a while, once you could get a really nice example for silly money, but the french were not as into older stuff back in the 1970s. They caught up fast, and, lets face it, if our choice bikes were as scarce as theirs we'd be the same.

Its the reason so much old  2 stroke tat is now dumped onto speculating antique dealers these days.

And the much stricter rules governing registration docs over there.

In reality it is quite easy. It clings back down the mudguard. When stopped, the driver is positioned behind, lowers the crutch and the ground with his foot and with his hand he takes the loop that is seen above the fender and exerts a movement backwards, this lift the wheel and the crutch pivots.
