The B31, during its life, had several frame types, solid, plunger and eventually, swinging arm
This bike was recently purchased by a local artist who specialises in art work on bikes and many other projects, see his link on this site, under Links: Custom Paint Work Specialist
A friend introduced us, as the owner needed help with the mechanical work, this is not a strong area for him, so I took mainly the engine and gearbox
Although the engine looks dirty there is not a lot of problems, just normal cleaning, refurbishment and recoating parts for the look, unfortunately the gearbox is another story.
The gearbox oil had completely dried out and the castings and all the internal parts had to be boiled in washing up powder and soda, the castings will be bead blasted.
The internal parts were boiled in oil, and then soaked in oil until its time to reassemble them
The wheels were in need of refurbishment so were stripped, the paper between the spokes is so that each view / side can be seen without confusion of the other side.
