For David Barnert:
Thanks for the suggestions. I checked both sites & found they had very similar instruments but nothing quite like mine.
I am attaching a picture if you would like to see it.
I also found that my wife's dad left a large box of old sheet music for the concertina. There must be 200 or so different songs. Is there any use for this old music ?
Do you know of any place where I could have my concertina appraised ?
