I'm thinking the batteries went on the floor in the space between the wheel well and the front wall. Facing the wireless table this would be to the left. And possibly two batteries to the right of table.

There is another bracket on the wireless table on the right side. It is a flat bar that goes front to back and has a long bolt with wing nut on it. It goes out horizontally. There is also a stopper plate on it. It appears like it may have a had some kind of cable reel on it. But I'm not sure if its original or added post army use. I'll post a picture shortly.
