That looks like a 105mm gun profile to me, but I'd have to see more of it to confirm, especially the fume extractor. Mind you, it is possible to jamb either a 20 pdr barrel or a 105mm barrel into the same breech and mounting.

I'm betting it's a "Tank, Medium Gun, Centurion Mk 11 LR".

The tank would be fitted with two co-ax weapons, but one is the Ranging Gun, the L6A1, .50-cal, which is restricted to firing 3-round bursts at each depression of the firing pedal (actually, to be precise, three single rounds, controlled by a controller box). So the .50 is not strictly used as a co-ax machine gun, hence the name 'ranging gun'. It was originally termed a Ranging Machine Gun, but the terminology was altered to reflect its true application as a ranging gun only.

However, the controller could be overridden by the loader/operator by hand, in which case the weapon reverted to true automatic operation.
