The metal parts of the webley should resemble blued steel which on my real one is a grey/blue satin finish. Some folks seem to think it should be bronzey, maybe cos many other flare guns are made of bronze or brass. I found Revell #9 anthracite or RAL7021 a good match to my original's finish A very light gun metal drybrush over the top, slightly heavier on the edges gives a good representation.
