Hinterlands Miniatures has some historicals models that are now available over in their webstore, including a camel train. Everyone needs a camel train, to be fair.
From the announcement:
I wanted to let the world know that there are new releases at Hinterland: a new cavalry pack with open hands, a pack of kneeling hussars, a pack of trench raiding riflewomen, and a Victorian camel train. See the store for details
