Many thanks for your helpful comments. I’ve managed to do a little research and started my figures, although progress has not been as quick as I hoped.
The photo (sorry about the quality) shows, the kit and size of figure, a basic figure, a figure with a changed axe, high heels and dwarf bread, and the start of a conversion to a knockerman.
The figures will represent a combination of the Copperhead and Uberwald miners in that knockermen and safety lamps will be represented. I’m not sure about the various items mined though; gold, fat and treacle, but might try to show them on the banner somehow.
The competition ends in a week but I don’t think I’ll finish in time – I will however post a photo of the completed painted group when ever that is.
