Info on HDD-825 and Hispano 30mm cannons?

[EpicBlitzkrieg87]

I've been reading about the Italian Aerfer Sagittario II and Aerfer Ariete jets lately, and came across their armament. I had never heard about 30mm cannons like those, and I couldn't find data/info on them using Google. Does anybody have info on them?

I can point you to a possible source: AG Williams' Rapid Fire.

Aside from a rate of fire of 1000rounds per minute I can find no other details in a quick look at "Hispano Suiza In Aeronautics" by Manuel Lage.
