An old, antique (but perfect) reed organ/harmonium (I'd have to check out types and sounds) that had the options of being either large and ornate or small and compact when I wanted to travel....could maybe even convert into a concertina!

I do have an old Mason & Hamlin church organ, very pretty woodwork, that my husband got in part of a barter, but, it needs a lot of work. I took it apart once to look at it, but, haven't gotten to it yet for major work.
