I'm considering selling my BOP vintage Ludwig set, which is a transition Keystone badge. Sizes are 22, 13, 16. All original except for the front bass hoop which was replaced with a modern one (by previous owner). I don't have a set price yet, but thought I'd get the conversation going to determine interest. I can post photos later on. I'd be looking to keep in USA and probably go via Paypal. I've picked a couple other vintage Ludwig kits that I'm planning to keep instead.
