Flak vierling

[stugumby]

Just out of casual observation here, seems the Germans went from 8mm mauser to 20mm and not much 13-15mm ground gun use at all except for late war flak drilling mounts. But why have a 4 gun mount that was fed by 20 round magazines instead of belt fed, or drum fed like oerlikon cannons were. Seems a bit over engineered then a slower rate of fire due to having to constantly change magazines, Overheating issues? Just the technology of the day?? Definitely a greatly respected weapons system that was effective.
