Thanks for that mate
So, chemically dyed it is then... sounds a bit like anodizing but without any electrical current being involved. I had a look at the Wiki page for anodizing earlier, I knew it was a common finish for ally but was looking to see if it had ever been used on brass, it's do-able (just!) but so uncommon that I was able to rule it out as a contender.
Mind me asking how you know about this process?
