The brake drums fitted to the bike had been incorrectly painted grey.
Stripping off the grey paint was a laborious process; between the fins being particularly time consuming.
The drums are probably the first parts of this restoration that are finished and ready to fit. Once dry, they will be stored away until re-assembly.
