Default Canadian Centurion tanks intercom system?

Perhaps the Canadian Centurion vets can help me out, what would have been the radio in place in Canadian centurions and what system was used by the crew to communicate? And we're these exclusively Canadian equipment or versions of US or NATO gear? I know it is easy to find the US Vic 1 and Vic 3 intercoms, would these have been the same or similar?

Thanks as always for the help

John

I was a crew commander in the Centurion Mk11 in germany from 69 to 72. The Centurion always had the Brit IC which was used with the C42 family of radios. They integrated the American family of radios (46/25 sets) with the Brit harness at the JD9, I believe. It worked great and in my opinion was superior to the US IC which I had as a Leo C1 CC 10 years later.

so did the Leo have US style radios and IC's installed from the start? I want to install a IC' in our Centurion, currently it has no radio, it does have some British IC boxes but how I would go about integrating components looks a little beyond me so I was trying to pick a system that would be simple and readily available. Obviously the drivers station has to go through the RBJ

would the Centurions in Canada also have used British Radio systems? I guess what I'm asking is, what would be the correct radio set for a Mk5 Centurion stationed in Canada?

The C42 was a pretty standard radio for the army in Canada starting, I believe, in the late 50s. In the early 70s, the US radios started to appear for the regular army, but a lot of the reserves continued to use the C42 radio until about 1980.

I have the equipment logistic directives at work for the Centurion. I am pretty sure it had information on which radios were used. I'll check tomorrow and post the results here if someone doesn't beat me to it.

While you don't see sales of the C42s that often these days, a big part of the reason, likely, is because they are so darn huge and heavy. Most guys don't want them in their jeeps. But they are out there, hiding in sheds and warehouses.

JD9 and RBJ? Please remember that there are some less acronym-ically minded members reading your posts too.

Thanks,

JD9 is the 9th variant of a "junction distribution" box. Basically a router for the radios and intercom (IC) system.
RBJ is the "rotary base junction" which is the unit in the bottom of the turret which connects the electrical services including radio and intercom between the rotating turret and the stationary hull. It contains a lot of copper slip rings and carbon brushes and is the limiting factor of how many radio functions can be routed between the hull and the turret. In WW2 British tanks that had hydraulic turret traverse powered from an engine driven pump the hydraulic circuit went via the RBJ too, making it even more complicated.
