Restoration update: My 1944 Triumph 3 HW Military motorcycle

Incidentally, this part was missing and had to be fabricated in the lathe to the correct dimension, which was again unknown.

BHPian cosmic_ocean recently shared this with other enthusiasts.

Update:

Clutch pack in, after using the correct oil return spacer at the clutch inner. Incidentally, this part was missing and had to be fabricated in the lathe to the correct dimension, which was again unknown. So I did some reverse engineering, by calculating the size of the grove under the spring plate and subtracting outer dimension at the return channel. Too big and the plate won't fit. Too small, and oil starts to leak when the engine runs. Looks like what I've made should be right. Will know for sure only once the engine is started.
