To make the limbers, I used models from the French Limber set. I found zero visual reference on how the riders should dress, so I used some swedish light dragoons to play the part.
I plan to give 1 limber for each battery in my collection - a battery being 3 cannons - which means all of my previous batteries that don't already have one will eventually receive theirs.
The swedish cannons got their limbers right away, and I chose to use 4 horses to represent foot artillery and 6 for the horse artillery - a recipe I'm probably going to replicate throughout my armies.
