Oh, man. The first spelling mistake I've made in months, and somebody notices...
Anyway, it was a Piper J3C Cub, PH-GEN. No saucers attached. I think it's actually fully original without any electrics (except a semi-portable radio on a battery), but it does have a tailwheel instead of a skid. (It's based at a field with tarmac, so I guess that makes sense.)
I now know what "adverse yaw" is...
