Mine is a Pearl River, which folds up small enough to go in the back of a mini!   I'm very fond of it, but after taking up the concertina, and inheriting my Dad's piano, I don't seem to feel the urge to play it, so it now sulks beneath my computer desk.

Mind you, it has sneaked out to Wild Goose Studios from time to time to play on various albums. It made a brief appearance on the Patterson Jordan Dipper album a few years ago, though it was mean enough not to bring me home a copy! It is still basking in the glory, and thinks itself a bit above me these days I fear!
