Finally have this bike in the garage now, stuff happened and it didn't make it here till now. The mag had a issue but once sorted it started second kick and motor is super quiet internal.
Needs general road worthy things like tyres etc but it would be pretty simple to get this unrestored road or usable ready.
All indications lead me , and others, to believe it is a 1956 trials replica, the lights, (battery total loss) ,seat and tool/battery boxes are retro fitted, the bike never ever came with a lights power source and the mag cannot be fitted with a kill switch function. The swing arm also matches the trials 350, the scrambler version was a heavier type, both front and rear guards are alloy. The seat is actually 1964 Lightning Rocket Clubman which i will probably use on my A10 cafe racer.
Where some paint is peeling off the frame it looks like it was once a bronze colour, it is very hard and may be possibly an original colour, does this ring a bell with anyone?
The eng num in G2-364, that's it, the frame is G2-11977, or at least looks like, hard to tell for sure till I scrape in down a bit.
