Re: CPO Uniform questions
All of his training appears to taken place at HMS Victory. Seems hard to find out about anything at the base as searching for Victory gives you the obvious results.
If they are common badges I'm doing something drastically wrong. I've been checking ebay for months and nothing. You get the odd Stoker badge, there's a PO stoker badge on there at the minute, but I've never seen a pair of CPO ones.
