My pal Penelope has one and I'm trying to make it work. It's clear that at some stage it has suffered a heavy blow of some sort. I have taken it apart and araldited together the inside of the bakelite case. I have ordered some electrical cable which should arrive in a few days. Apart from the case colour (Pen's is green) it's identical to the dark brown one that occupied our mantelpiece when I was a small Bagger. My recollection of ours was that, once you got it going, it was very good and worked well, keeping good time, but it was a bugger to get started. I'm pretty sure that on one occasion it went backwards.
On the back it says 200/250V 50~. What is a ~?
