I picked up this concertina on Ebay. It seems to have been made by Stagi for Matusewitch Associates, New York. Is anyone familiar with these instruments? It seems to be higher quality construction than the 1970-80's Stagi that I've seen.
The box appears to have been stored in a basement and will need some restoration. The hardware is corroded but most of the reeds are in good shape. I'm trying to estimate how much I should put into it. I purchased it for $179.
