Krakatoa's revised pom-pom and his earlier comments have made me rethink the pom-pom.
I've taken the version he has recently posted. I've amended the current part with a smaller mount (length and height), revised the sight and the barrels and altered the feed layout of the octuple. I couldn't bring myself to adopt the single-pixel barrel, although I've made the 'muzzle' smaller now. The pom-pom was a chucky weapon and I feel the drawing should represent its "character" and help it stand out from the Bofors. Anyhow, I'm open to further comments and ideas.
