Thanks guys
a few more pics, marking out the circles for the inserts, so i could hand paint them.. these ones the black was too hard to see, or sanded off so i had to mark out where i had to paint to with a sharp pencil and a math-o-mat. there was still a little bit of tidying up of the black to be done when the last pic was taken, where i had gone outside of the lines slightly. This cleaned up nicely with just a bit of scraping with a scalpel.
