The anti-tank capabilities for both the Soviets and Germans are finished. The FiB metal kits were a little bit stiff to put together (lots of trimming on the barrels). The primer also peeled off at some places, but I guess that's the paint's problem and not the models'.
Used a sepia wash on the Soviet crew and a black glaze on the Germans for a quickshade.
The 45mm gun was a PSC single sprue bought on ebay. It was confusing because it was stated that the item is new, in original package. Now how can you get a single sprue without opening up the 5-gun pack, I have no idea. The price was still OK so no complaints.
