The Mark II Missile Turret from Puppets War does a pretty good job of turning a Rhino/Razorback into a Whirlwind. The design would work quite well on Deimos-pattern Rhinos.

Thoughts on the painting of, and playing with, toy soldiers.
Hi, how much conversion was required on the rhino/razorback to attach the turret?
None at all – the turret is completely compatible with the Razorback door panel.
