Horse drawn limbers were used by most armies in WW2 and are likewise available in most Bolt Action Army lists. They can pull any sized gun onto the table, albeit slowly, for a cheap point cost.  There are a choice of horses within the folder. You just need to print whatever two you prefer. A base plate is included to mount the model, which can help protest it in use and when in storage. The test prints in the photos were done in filament, but I have included resin files, plus pre-supported and hollowed resin files.   There is an additional piece which will allow you to make a four horse team if you so desire. You will want to print both horse teams ("A" & "B")
