"Spanish Civil War CR-32 Armament" Topic

Does anyone have reliable information on how the CR-32's sent to Spain during the SCW were armed? The Wikipedia article indicates that the original CR-32's were armed with either a pair of 7.7 mm MG's or a pair of 12.7 mm MG's; and that a CR-32 bis model (apparently for close-support work) was developed with a pair of each type; and that a development proceeded to the CR-32 ter model, which was the model send to Spain during the war. The "ter" model was an "improved CR-32 bis with many improvements", apparently including an improved engine, gunsight, instruments and a strengthened undercarriage. This would suggest that the CR-32's sent to Spain had 2 of each type of MG, but the photos I've looked at don't seem to show wing-mounted MG's (presumably the 7.7mm's). Does that mean they had 12.7's or 7.7's mounted in the fuselage?

I think they're mounted in the nose, over the engine. There are people who know a lot more about this stuff than I do, though!

The CR-42ter was armed with a variety of MGs, one suite
included 2x12.7 mm guns mounted normally with another
2x12.7mm guns mounted in underwing blisters.

Of course, the CR-42ter was not available for the SCW.

According to Howson – Aircraft of the Spanish Civil War – the Italians supplied 184 CR32s, 12 CR32-bis, 37 CR32-ter and 144 CR32-quaters. The ters and quaters were equipped with 2 x 12.7mm Breda machine guns. There is no reference to wing-mounted guns; the major development of the CR32 in general from its pre-decessor the CR30 was the use of synchronised guns firing through the propeller. The CR32s had two machine guns, either 2x7.7mm or 2 x12.7mm or one of each. The CR32-bis appears to be the only variant with four machine guns, in other words with the underwing blisters.
