I picked up a repro MARX limber and cannon set and added a "extra" two horses to make the correct number for a six horse team. It's a nice sturdy "toy" model that's stronger than the 1960s MARX play set version that broke on Christmas morning 50 years ago. (Yes 50!) The thing is 17 1/2 inches long making it hard to add any more to the battery in terms of table space. I'd need 5 more limber teams and six more caisson teams just for the Union side. Too much $$$$ and space are needed.
I looked up a period artillery manual on-line to see what the actual distances between guns and limbers was.

You really need more that a 8 foot by 4 foot standard plywood sheet to hold a 54mm/1/32 battery even without the line of caisson limbers behind the first line on limbers if you set them up in scale.
I'm guessing that a war game scale battery at 28mm could be set up in scale but that might defeat the purpose of war game figures.
