It's been a little while since I updated this, so here's a quick progress update.
Firstly I was unable to satisfactorily tidy up the original zolatone paint work, it was badly faded, there were lots of chips and some quite large rust spots. So for better or worse I opted to get it sandblasted and powder coated.
I opted for RAL 7016 Anthracite Grey. I also ordered some reproduction decals from Gil - so there's a nod to the original colour scheme.
I think I got the decals in the right place and I'm pretty happy with the results.
Next job is to clean up some parts - Crankset, Brakes, Shifters and Wheels.
