I'll answer both questions with one post, as I'm on my phone(tiny keyboard).
I make the 1st Corps Vehicle and figure range also their tents,jeeps,elephants,part of the new dark age range and related buildings,to name but a few,infact if you take a look at the Free(ish)vehicle offer you can see some pictures of my work from my own collection.
Theres a 28 mm Sopwith Camel,People say you can't make 28mm planes,You Can infact you can make the whole plane in 2 parts (not including prop.)
As for where in the Riding I live in Hull,less than a forty second walk from the North Hull Wargaming club.Ironic they like to game 15's&20's and I prefer 28mm.
