EMS KS Knob-Thing? where to get those?

anyone here knows how to get one of these? it’s a AKS Modular Synthesizer/SEQUENCER  „Knob“ which is special – but maybe someone knows a nice replacement? I’d prefer some normal shops than to worship that Rehberg-Guy..

Sent my Request to Mr. Wood, but just in case there is something, let me know..
