Welcom To the forum Tom. The support for the Hammonds are a bit tough. I recently was looking for the reed plates for my Hammond 44 and Hyper, and I contacted Hammond Suzukie USA of which it took about a week to get back to me with the response of “call the dealer” Unfortunately they don’t sell these products in the USA anymore. But I did contact some of the stors in Japan via email and they were able to get the plates and gaskets to me in about a week. They told me that all parts are available. So I would ask the store you are planning on purchasing it from online if they are able to do so.
I love the Hammond Melodion and own all of them.
