Thanks guys for the encouragement. The reference to the 1960s magazine was a boon, I have a copy of the magazine which I found in a box of stuff from my younger days, it must have been about the first model mag I bought. I now have the basic lines and enough to make a start. My only problem is that I haven't finished my current project, a gentlemans electric yacht from Edwardian times. I always do this, get enthusiastic about the next model before I finish the current one. At least I can begin on the paddles etc as a change from all the varnishing I have to do.
I'll keep you posted when I make a start, there is such a lot of help available here and I look forward to being able to access the download info.
As for the smoke, I think they must have been burning old socks, and I've never heard of a unit for models that does that.......... Unless you know better.
