These unpainted cast metal figures and kits are typical of those offered by countless British cottage industries. However, there's no ordering (or any other) information about these products on their website. So, for the time being you'll just have to click the company logo above and enjoy their photos (the sample below is from D.G. Models). Incidentally, I've attempted to contact D.G. Models, with no reply.
Where to Buy
You'll need to get in touch with D.G. Models to determine the availability of these items. Good luck with that.
