I've recently finished the first draft manuscript for a murder-mystery set in England in 1923. While writing it I thought it would be fun to have some 28mm figures representing two of the characters, and a model of the car they drive, the 1922 Rover Eight. Yes, I do have Pulp Alley games in mind!
The figures are no problem: Copplestone Castings have just the ones.
Here they are superbly painted on Carmen's Fun Painty Time blog.
What I can't seem to find is a model of the 1922 Rover Eight in 1/56 scale...
