Here is a terrific stagecoach from Processed Plastic. They made this in a couple of color variants and I'm pretty sure there's an all brown version buried out in The Cave somewhere but I din't feel like mounting an archeological dig to find it LOL It has opening doors to accomodate riders (MPC 60mm ringhands would fit in here nicely - but the peg-butt ringhands would need to have the pegs cut off), molded on baggage on top and the horse hitch has a fifth wheel guide allowing for smooth rolling across a flat surface. The seated driver is a bit tricky to measure but after fiddling with the ruler, it appears he's 60mm.
Overall length is 11", Stagecoach body 5 1/2"L x 4"H x 2 1/2" W. Enjoy! Opa Fritz
