I've just finished these figures in a mixed group someone sent me. I am not sure, but I think these figures are from Perry miniatures. There are some other Perry miniatures in the figures I received, but none come close in terms of the quality of the casting. If all Perry figures were like this I'd never buy anything else.
I made the fence from 2.5mm thick 3 ply wood. I'd seen something similar at the Tripples show in Sheffield. It makes a nice prop for photos, and works with everything from 15mm to 40mm, depending on where you place it in the photo. With smaller figures I put it in the 'distance', so that the figures don't look out of scale.
