I hope Malamute's flyer is well armoured! Prussia definitely has an advantage in the arms race with this. I like your use of WW1 figures repainted to a more VSF looking uniform.
Not knowing too much about WW1, I assume there are differences between them and late 19thC, but not too glaring? I assume the weapons would be different, but again WW1 would not be too different in looks from 19thC?
Would 1914 German infantry, Uhlans etc do as 1890s equivalents? There are a lot of very nice early WW1 figures, which I'm tempted to use for my VSF gaming.
