Lachenal 20-Key Anglo

I'm selling my Lachenal anglo (#132195). I purchased this refurbished from Barleycorn in Oct of 2021 for £600. It's got concertina reeds, has barely been used, and is in fine shape. The wooden case, however, is not. The bottom is falling out and I wouldn't be trusting it at all, so I keep it in the box in a soft carrying case which would come with the concertina of course. I can send it within Switzerland, but haven't got the shipping quoted.
