Back to the present, the rear fender is looking a lot more like it should and I'm quite pleased with it, not absolutely perfect, but near enough that it won't stand out too much.

I bought a fuel tank for not too much money a few months ago, not too badly rusted inside so I gave it a soak with a Deox-C solution which not only cleared the rust, but also exposed a leak next to one of the chrome side cover mountings, I made up a small plate and brazed it into place this afternoon and it's currently sitting on it's side on my work bench with a half gallon of kerosene testing for a flaw in my brazing.
