I too would like to have mules for my mountain troops and I think you guys are really onto something here.....
The question is, how can it be packaged to be most profitable for HaT..
yes mules could be marketed with something else that would sell..a wagon of some sort or a mountain gun. Could be cool.
Alternatively, what about a draft animal set? Some combination of mules, oxen (also hard to get in 1/72), baggage camels (a set that has been lurking in the HaT queue for a long time) and maybe draft horses.....I am guessing many of us would be interested in these as well as mules? So maybe they could be combined into a single set.......
