I've been working on these recently.
Museum are very nice. My only gripe is that they are very large figures. I bought some which I won't be using as they don't mix with the rest of what I have. The wagons with the hinged cover are shown in various modern publications but I've yet to see them in any contemporary source – I'd be happy see some as they do look good.
The Minifigs figures are good and there is quite a variety. The moulds are getting a little old and the shafts of weapons such as flails are rather weak but they do a lot of specific Hussite and related figures. I mostly have the melee infantry as there is more variety than with the shooter. The knights and other mounted in the range are very interesting, with specific German and Bohemian fashions. The range includes some good civilians who would be suitable for a number of 15th century armies, plus a bunch of priests.
The war wagons are good, even including the pierced plank to go under the wagon. The artillery wagon is based on those in the late 15thc Hausbuch. There is a good variety of artillery available.
Essex are pretty good. I am going to mix them in with others are the poses are a bit limited. They do specific Hussite infantry and cavalry. I don't have their wagons.
I have a few of the Irregular Hussite shooters. I like the poses though the detail is a bit less defined than some ranges. The wagons are very good. Their artillery wagon comes with a couple of trestle mounted guns in an otherwise standard wagon. Almost all of my wagons are Irregular though I may yet get some more Minifigs.
QR Miniatures do a couple of suitable wagons. Each pack contains one with horses etc and one which is supposed to be emplaced with wheels partly dug in. I have some – they are smaller than Irregular and Minifigs so they may end up being used for later Hungarian wagons (with later looking crew). The range is intended to be mid-15th century so after the classic Hussite wars periods, but some of the foot are suitable.
Vexillia does some early 15thc Mid/East European shooters which are suitable. Some of the Mirliton and Donnington figures are also suitable. I'm using a mix of these with the rest of the above and I think they match pretty well – and I think I'm quite fussy.
Vexillia and Fighting 15s both do Poles who will work not only for some of the Bohemians but also for the Polish contingents aiding the Hussites at various times.
15mm.co.uk do a range of Hussites. I _think_ these are quite small going by some other miniatures I have from what was the old TTG range.
The new owners of Thistle and Rose told me that they plan on releasing the Hussite range some time, perhaps later this year. I've only ever seen the wagons and they seem good.
