Thanks Norm, It doesn't try to hide the fact it is very "utilitarian", and that is one of the things I like about it. I did get a belt cover made by a local engineer for that top pulley, but still haven't got around to fitting it.
Here are the two manuals. Judging by the numbers on the back, one was printed in 1975, the other in 1991. As I have said previously, I am still chasing a manual for the very early Rover Rider model. If anybody can supply one, please let us know.
