Many thanks for the reply. I have since learned from Mike Powell that my bike wasn't a Comerfords, but appears to be heavily modelled on one. The forks are Ceriani which Comerfords didn't use and the tank is different, but otherwise it looks the same.
I am in no way disappointed, I just like knowing the history of my machines.
Now starts the fun business of restoration and having a nicely turned out bike that I can be proud of.
