I was at the council dump at Exmouth on Friday. This is one of those places that accept junk and turn it into gold, then sell it. They had a pair of Stuart magneto engines, both slightly disassembled. I think there was one magneto missing and maybe a few other parts.
If they'd been cheap enough to throw away, I'd have had them .. but not knowing much about them, it didn't seem worth the risk. However, if anyone wants them for 25 quid each (maybe a bit less if you haggle) they're probably still there.
