"Models worth fighting for."
Ironclad's Victorian Sci-fi range has a few potential VBCW figures, including British line infantry and Grenadier Guards in home service uniforms for those of you who like a dash of red in your faction. In the Odds 'n' ends section, potential militia figures can be found in the form of Victorian thugs, Victorians armed with sporting guns and armed servants.
They have also started work on a dedicated VBCW range, with excellent packs of armed miners, telegram boys and even firemen!
Irregular have a small VBCW range, currently consisting of some armed policeman (with a wider range in 20mm), which can be used in conjunction with the figures in their Emergency Services range.
Irregular Miniatures also stock a range of 25mm WW1 figures, including British and colonial troops, which might be a useful source of regulars and territorials.
