[For Sale: 60b MacCann Duet]

The delicate ends, the chambers etc have a strong resemblance to a recently listed (and sold) Anglo on Ebay that was subject to discussion elsewhere on Concertina net (sorry, couldn't find link). This too was un marked with Jeffries proposed as a possibility.

Your similar Duet looks a very nice box.

[Unusual, interesting concertina]

In response to a question the vendor says the ends are 16cm in width. Perhaps too small to be a bass?
