Vintage Hohner Corona II Accordion/Concertina - Black

Vintage Hohner Corona II Accordion/Concertina.   This vintage accordion measures approximately 12.5" high, 12" wide and about 7.5" deep.   The leather hand strap and the two small straps that hold the accordion closed are intact.   There are 31 buttons on one end and 12 smaller buttons in the other end.   Front of accordion reads: Hohner Corona II.   I'm sorry, I don't know how to play the accordion;  I can't tell you if it is good tune or if it works correctly, but it does make various sounds as I open/close the bellows and push different buttons.   I have stretched the bellows and I don't see any obvious damage to the bellows.   The body of the accordion is black and it has a metal grill; this metal grill is pitted and rusted/corroded (see close-up photo).   Four of the seven tiny screws that hold the grill in place are missing, but the grill is held securely with the remaining 3 screw.  Sorry, there is NO shoulder strap and there is NO carrying case included in this auction.  NICE VINTAGE ACCORDION!      NO RESERVE!!!  We combine shipping and mail world wide!
