Terminator 3D: Battle Across Time, Mini Hunter Killers, earliest design, from T2:3D, T23D

original production material

One fully painted up Mini Hunter Killer from production. It includes a metal blade that actually spins.  And then a complete but unassembled Mini HK.  

The painted up Mini Hunter Killer was the initial design before the barrel was slightly modified.

I've been told James Cameron designed the Mini Hunter Killers.  I once owned 3 from the Universal Hollywood store.  1 end up with Paul Francis and the other a private individual on Ebay.  If you have one of his Pauls castings, you have the later design.   The main difference is the barrel design, which I like a little better ;)
