Reply To: Hohner bass melodica
The bladder on my Suzuki B-24, which I bought a couple of years ago, looks exactly like the one on your Hammond, Melodica-Me, with the same oval washers. I’m guessing that yours is older, and that the current B-24 is close to the Hammond BB-24 and has the same bladder. The bladder in mine is marked in white with “23.9.26”.
