I thought all machines ending in 5 (05, 35, 45, 55) were Unibus.

>From what I've read (and I've seen a manual with a sketch of one), there 
were going to be 11/09 and 11/39 machines. These would have been 
'packaged' versions of the 11/04 and 11/34 (much as the 11/10 is a 
packaged version of the 11/05). In the end, I don't think DEC ever 
shipped a machien with that nameplate, they were all marked 11/04 or 
11/34 as appropriate.
