Please remember that the III-A was not built in full dynamic balance, nor with those concepts fully understood. The monitor for example, hangs off of the bottom center line of the face. NOT anywhere near c.g. If you were to turn it at all, the rig would go very much off side-to-side. Similarly, a tilt in the monitor has the same effect almost ( almost.... ) as a tilt from the old black bar CP Steadicam batteries.

The for and aft racking on the bottom is a beautiful step towards finding a good d.b. I am guessing you can get it into good d.b. but to be honest I have never tried with a stock III-A.

Has anyone, and how was it achieved?

With the Bottom gear rack and AB batts you could dynamic balance the 3A.

FYI-

The first rigs we (anyone) ever dynamic balanced were 3A's... so it's quite possible... certainly with the fore/aft rack for the bottom electronics and battery. It might also be possible without that rack, but there would be a limited range of positions for the battery and monitor.
