Did ILM utilize any standard mount types when designing the armatures for the original SW models? In most of the images I've seen there's just a round pipe and it slides onto a motion control rig. The motion control rigs must have had a finite set of connectors. How did they lock the model in place? Did they have clamps or locking pins? Was there a standard size?
There is so much fantastic information documenting the model kits used for the 32 inch Millennium Falcon, but I haven't seen any mention of this.
