Hardly copying to put more than 1 barrel on a single anti-aircraft mount.
Everybody had
mobile anti-aircraft guns in WW2.

But quad 20mm/23mm mount centered on a tank turret is a rather unique
configuration. Besides, Wirbelwind and Shilka, what else was there?

Never heard of a Maxon mount?! 4 .50Cal's in a turret, often mounted on
half-tracks. The russian
equivalent used four 14.5mm KPV heavy machineguns. The shilka was actually
evolved from a twin 57mm
anti-aircraft gun, the ZSU-57. Whereas the ZSU-23-4 is based on the PT76 hull,
the ZSU-57 is based
on a T-54 hull.
