Most of the wagons and baggage bits are a hotch-potch of stuff - E.g. the camels are Perry Beja Warrior camels with Milliput and balsa baggage bits added at home. The carts are manly Irregular Miniatures bits and pieces - the sides of the one in that shot are actually bits of their ladders. Boxes, crates and stuff are Irregular too, in the main.
The brown and white oxen are Foundry - I originally bought them for West Country ECW limbers and re-purposed them to this project after a new paint job - but, I can't remember what range.
The wagon and oxen are of different bases.
