You are looking at a rare colorway of the 3 Knob compressor from the early days of Keeley. I could not find much information on this pedal so I will describe it to the best of my ability. It features 3 knobs which seem to function as a typical 3 Knob compressor with volume, sustain, and attack. It works properly and sounds great.

The only markings I found on the inside in marker is CBM, 00047, and the date is either 1-20-13 or 1-20-15. On the back plate is a metal engraving with the number 8.

This pedal will ship well-packaged and fully insured for $15
