I have an old Beseler motor base and an 8x10 Unicolor processing drum that I acquired from an estate. The drum appears to be clean, and the top fixes on to the drum OK. The motor base works; it turns when plugged in and turned on. It only goes one way (at least I couldn't find a way to reverse it). There is a leveling knob. Both for $30 shipped to Conus (PayPal OK), or $10 picked up in Westerville, Ohio (near Columbus). One week only, after that it goes on the curb.
