What firm produced H-S 20mm cannons in UK, what were montly production rates?

I have no idea what other companies produced the H-S but I do know that BSA made 42,500 guns of this type. Others must have been invovled as this wouldn't have covered Spit production needs let alone all the other aircraft who carried this weapon
