Rare and available... en France!

I always enjoy perusing the available instruments on a French diato site.  There are almost always instruments that I have never heard of before, like this very fine looking Martin 2 1/2 row.

I can't vouch for the quality of the individual instruments (and of course I have no financial connection to the sellers), but I can say that if you are looking for something unusual, this is a good place to check.  I've seen Castagnari mixte accordions (diato treble and stradella bass) as well as oddities (a Castagnari with 30 basses -- 3 rows of 10, bass/major chord/minor chord but not stradella) and some of the brands that we see less frequently in the US (and likely, the UK).
