I had warned his wife that I really don't know much about selling used drums and drum gear.... the reason? - I've never done that. I've got every piece of drum gear I've ever purchased... now "where" it is is another question. Some here at home, some down in my old shop... in the granary, maybe my old office... any of several places. I don't know.
I did donate some 'roto-toms' to our HS some years ago and I regret doing that.
Every so often I wish I had them.
