Sitting between the standard 1:12 and the big display builds, 1:10 is a scale that turns up rather than being planned for. Kits appear when a manufacturer chooses the size for a particular machine, so what is listed here follows current production rather than any settled range. If nothing here suits, 1:9 is so close in size that the two mix on a shelf without anyone noticing, while 1:12 offers by far the widest choice of machines.
