Ah Ha!
Good evening everyone from Cornwall.
Now I only have to work out how to post photos.
I took Chuck at his word as to the cost of shipping from the USA and bought a Proxxon scroll saw and an 8' x 4' piece of Russian Birch ply (for I guess about the same cost, and began work on January 5. I've broken about 8 blades, exhausted ferocious concentration, still have all my fingers and I'm quietly pleased with the result. I'd put up a picture but that may have to await the return home of one of my children to show me how.
