Where can we get Cold Blue? Attn Alan Maisey or anyone who lives in Australia

You're welcome.

Yeah, it does a nice touch-up job, one of these days I'll try it on a complete blade.

I don't have a pen, I've got a very small bottle of the stuff, near as I can figure I've had that bottle for close on 50 years, and its still got about a quarter in it. Mostly I use it to touch-up my rifles.
