these russian rail kits are by UM Military Technics, which is a group that splintered off from UM, and not surprisingly are still referred to as UM by many sites.
I've built a few UM MT rail kits and they are of a good standard - equal to UM or better.
I haven't built this particular wagon, and dont have it in the stash but it seems it does have the spoked wheels, its based on UMmt Kit 614 (two axle short pilot car).
The kits I've made from UM (mt) have virtually flash free parts, the parts can be a little too firmly attached to the sprues, but thats nit picking.
With the long fully enclosed body shells on the armoured wagons there can be some issues getting a flush fit on all 4 sides. This one being an open wagon with small boxed fighting compartments seems unlikely to have that problem.
I have the two axle long pilot car (UMmt Kit 615) unbuilt and have put a picture below so you can see what the spoked wheels looks like. The flange is a realistic looking depth, maybe a micro miliimetre too thick but a light sanding on the reverse (inwards) side will sharpen the flange, though it scarcely seems needed. References on russian railway wagons are scarce, so can't comment on accuracy of these kits.
Henk's website has the full instructions and other details of the kit in the below link, to give you an idea of how detailed it is. Scroll down to bottom of below link
