An unusual machine I will be working on. I have never seen an engine like this. The top end is all alloy. Anyone know anything about it?
Sorry, it would seem I cannot add pictures at the moment for some reason, but imagine a Model G engine, with all alloy top end ...

I found the image a while ago on Red Devils motorcycles website- here is what they say about it:

" Mine for the last five odd years and featured in earlier posts, my Model G trials is up for sale. I got it from a chap who lived up in Redditch who had put it together in the eighties. He won a lot of events on it. I have won none! In fact I haven't really used it enough and with an imminent arrival in the shed it needs to find a new home...

When I got it the Model G sported girder forks, I wasn't too happy with the geometry of them and although previous owner had proven them to work by winning I found them difficult so have fitted a pair of Indian Enfield teleforks (better than the Redditch ones as they are double damped). I also fitted a more attractive tank and exhaust. The bike is a bitsa, the engine is a Model G with an ultra rare pre-war Bullet alloy top end, the gearbox is Clipper and the wheels Bullet. The frame is a Model G. Geometry is spot on for trialling but it is a cut and shut job and function over form, should you care to it could be tidied up. Engine tune is for stump pulling torque and it will mount most rises at tick over with the ignition slightly retarded. It is not road registered."

Sounds like you have the pleasure of working on the rare 1939 alloy type engine, I think the image upload function should be working now and hopefully my image attaches to this post which shows an old factory shot of this engine type.
