Is this a Canon triple set up or?

I can't see much of the manifold(s) in your picture. I've never heard of any Cannon manifolds except for M10 4-cylinders. Those I have seen were one piece for both carbs.

The manifolds on my engine, supplied by Korman when they built the engine in 1980, have an individual manifold for each carb.
