Vintage Simmons Drums (UK) Users Group

Hi folks,

There's a seller on eBay who is selling what he believes to be a
prototype of a rack mounted analogue Musicaid Clap Trap:

Any list members heard of such a thing?

(Won't be bidding myself, as thanks to the kind assistance of Jesper I
now own a Musicaid Clap Trap that was recently for sale in Scandinavia).
