The MiG-3 also usually carried 3 guns in the nose above the engine (2 ShKAS, 1 UB). The La-7 had usually 2 ShVAK 20mm guns, but by the end of the war versions with 3 lighter B-20 guns appeared. The post-war La-9 and La-11 had 4 NS-23 23mm guns.
I don't know if that is among the reasons why some air forces favored wing guns and other fuselage ones, but I think I once read that Soviet pilots who fired at close range complained about the disposition of the Spitfire's armament. I suppose it's possible that air forces that emphasized deflection shooting preferred wing guns which covered a wider area...

The La 7 is nagging at me - there were versions with three cannon in the fuselage and others with either two or four. My books are temporarily out of reach.

I have a trivial but perhaps interesting follow-up to the discussion about Russian fighters carrying more than 2 fuselage-mounted synchronized cannon: I just discovered today that the
IL-2 Sturmovik 1946 WWII combat flight simulation game models several versions of the La-7 fighter, one of which carries three 20mm cannon in the engine cowling. The model seems visually accurate, down to the assymetrical configuration (2 on the left, 1 on the right) of the cannon. For those who are not familiar with this aerial simulation game,
IL-2 is amazingly historically accurate in its attention to detail in the aircraft it models, some of which are historically obscure, as well as the simulation of combat flight.
