I've been thinking of getting some 10mm wargames figures - maybe Pendraken's World War One - don't know - I'll have to buy some to see what they're like as there's no photos on the web. Vehicles would of course be micro in size.
Irregular Miniatures 10mm range
Noticed that Irregular have started a range in this scale. Early war Germans to start with - see pic.
There's a trench system available too from Mark Biddles. This small scale would be suitable maybe I'll actually buy something but it might be just another project I don't get round to.
