| Extra details | When returned from the restorers, C & G at Liverpool, I realised I had made a mistake in asking for the chromed head lugs to be lined. It looked so wrong I painted out the lining where the frame was black and I was able to match the paint. The head lining didn't look quite so bad and I left it as it was as it would have been difficult to match the violet paint. |
Thanks for reading
