Really cool, Gribb has written that there will be separate arms with lance. I hope that heads with bushy mustaches are also there.
There will be separate arms with sword, lance and carbine. 2 variants of each to avoid a too generic look.
The lances will be provided separate from the arm unlike the gwm variants.
Steve will add bushy mustaches and some with beards on the clean shaven heads before they are released. To maximize the variety.
In total there will be about 8 heads with and without facial hair.

^It would not be a proper Hussar unit without facial hair like these guys were sporting.
Would also be useful to provide stahlhelm head as well. There were still some mounted cavalry right up to the Armistice (and beyond, on the Eastern front).
That is pretty interesting and I will mention it to him. Thanks for the input.
If there is a lot of interest for this it would be great to have others join in on commissioning them. There are plans for dismounted versions as well.
