Ooh, if only you had asked me a few years ago!
  This is a 3rd party quad height unibus board and
appears to be a 4 
port SLU.
  The manufacturer is ACT, and the only part numbers I
can find on the 
board
  are 10015000, 10015001, and 10015002. 
These were very common for 20 years as DL11-alikes.
You might have better luck if you identified the manufacturer as "Able"
instead of "ACT". They call it a "Quadrasync".
