I had a chat with the sculptor of these: Francesco Pizzo. It seems like he did them a few years ago - when he ran a small company called ‘Cyclopes forge’. He sold it to another company called: ‘Arcadia Miniatures’. I’ve never heard of it - and cant find any information about them, but according to Francesco the idea is to do a small line of Chaos Dwarfs casted in resin. He mentioned warriors, scouts, hero, mage and priest.
And a few facts about these Crossbowmen. They are 28mm scaled. Casted in white metal. Approx 23mm to the eye and should be of a good quality. I will try add better pictures when my set arrives
