MAKE ME A SENSIBLE OFFER ANtique Hohner button keyed accordion black !

BUtton keyed hohner accordion in working order. I do not know what key it is in someone has asked previously i think it is just in C tuning. THere is a bit of tape holding top corner as can be seen in pic but that is only because a small screw fell out and i did not have the same size to fit. This is an old accordion and nice decoration on it too. if the ad is live the item is still available thanks
