Update

Progress on a number of fronts this week.  Firstly, I've got the parts back from the platers, so I can start on rebuilding the speedo. 

The crankcases are back together, with everything moving freely.  The build up of the engine should hopefully move quite quickly from this point.

The sprocket carrier is all cleaned up, with a new bearing fitted.  I can now fit the rear wheel properly, instead of the quick lash up I had before.  There are some differences in gearing across the models, C110/C114/C102 etc.  The gearing fitted to this one when I disassembled it was 14/40, whereas standard should be 13/40 (I think!).  Once it's on the road I will probably have a play with the gearing to see what suits it the best.

Finally, I've sprayed up a number of engine and chassis parts to give them a better finish.  I booked an hour in the oven to cure the paint and they've come up really nice.  Was a bit stinky in the kitchen for a while though!
