I am looking to sell my grandfathers concertinas that used to play in polka bars around Chicago.
I went to Italo-American Accordion MFG. CO. to find out the quality and value of this concertina and this is what I learned:
B flat
5 press G
Right side not in tune
Switch maybe not working (Switch high ok but low not good)
Quad voice
high and low switch
Information found on concertina:
Star 1040
