Pretty hopeless, but my great aunt Ida Stern played English concertina in Brooklyn at least till the 1960s and 70s. I don't know if she brought it from Russia. My Mom had it after that and sold it to a music store in Oakdale, NY, which store doesn't exist anymore. This picture shows her with her two sons who played piano and violin, and apparently mandolin. I know she played in a mandolin orchestra in NYC; back then there were many of those.
If you have any clue about this concertina from the picture, let me know. I don't have a clearer picture.
Thanks for any ideas! I play now, though I hated the sound as a kid!
