Unknown CDC unit , looks like a drum memory ?

[jos]

Visited an older collector recently, and in his shed he has a strange thing, labeled CDC, that somehow looks like a drum memory, but then again not ( drum looks too small to be usefull )

The controller that goes with is  a transistor based  monster on countless small pluginboards.

Anyone can identify this ?
