It looks to me like a standard Unibus expansion chassis (a BA11-KE, as the
auction says) with a 9-slot DD11-D backplane and a pair of 4-slot
backplanes (not sure what they are, they may also be DD11's, I'm not good
at identifying them from the back ;)).  It could potentially be for an
11/05, but only if that 9-slot backplane isn't a DD11-D and is instead the
special backplane for the 11/05 CPU set...
