This version of the CN-86, painted blue, seems to be different than the unit in the b/w photo above. Can anyone explain the differences? Contact: jerry.proc@sympatico,ca (Photo via Kijiji,ca)

At the left are a pair of CN-86's in their native habitat - the bridge of a ship. Such was the scene aboard the icebreaker Camsell, radio call sign CGCW. One of the CN-86's was remoted  to the "Monkey Island"  navigating position, while the second unit was remoted to the Captain's cabin. The Camsell had just come back from a three month stint breaking ice for the Arctic resupply during the summer of 1968. The photo was staged for the magazine.
