Thanks for the offer of help JWO, much appreciated. I'll probably be taking you up on that! I had stumbled across Dragonfly and agree, very helpful website.
Hopefully, the previous owner should be sending me a new log book as he had already applied. Might be a problem though as my frame & engine number indicate a 1967 machine but the number plate is a 'D' reg which is 66.............have to wait & see.
