This started off life as the back of a clip frame with a couple of bits of cork board stuck to it, covered in scenic scatter and bicarbonate of soda sprinkled over it through a small tea-strainer. However, the model I was going to display on the base (the MiG-3 shown on this site) turned out to have a yellowish sheen which was only highlighted by the base, so it was shelved until now. I'm not sure what to make from it now, but it's definitely on the cards...
