This picture was sent to me by Robert Wallis.  It is of a Swedish
accordion.  He writes, "I took the photo in a music store in Stockholm
about 2 years ago [1992ish].  They wanted over $1200 US for the
instrument, so I had to be content with a few minutes of playing and a
photograph. I don't know if the type of accordion has a specific name,
though the manufacturer is Hagstrom."
