Living in southern California, it seems these kits are everywhere. Some are in scale for 28mm, and a couple of others would be fit for 15/20mm. Some of the original missions where very small, and many of the kits would look a bit strange on the table. Pegasus hobbies also does a lot of accessories for mission dioramas, including priests, indians, cactus, wells and wagon wheels, though most of their items are in a "toy" scale. It is somewhere between 1/48 and 1/32nd.
