Colouring is a totally separate process from anodising and many cock-ups occurred where the badge has been anodised and not coloured and then sealed which prevented the badge being re-coloured. A lot of these badges are sold as 'rare' officers versions and are deemed to be silver although Blind Freddie could tell the difference if placed next to a silver coloured A/A badge.

[[As far as I know only aluminium can be anodised.]]

With regard to K+K and A/A badges. All I can say is that I am very disappointed with the level of accuracy in this book and have not used it for any material in my current project. It may be better with non A/A badges but that is a subject that I know nothing about.

Andy - might have a small job for you for the weekend...

Hi Chris,

You've done such a wonderful job with the research etc into your new book that I'm almost afraid to make this point, I'm now going back over thirty five years to before I started welding.

I was, previous to welding, a metal polisher for close to ten years and if I can remember correctly ( and there lies the problem ), I was under the impression that anodising was a form of electro-plating and yes, mainly, in those days, for applying a coat to, for instance, door furniture etc.

I am however, certain that the process used then, could also be used on brass and other non ferrous metals, I am open to being corrected but I'm sure I'm right, hence my remark to Griff that anodised doesn't necessarily apply only to Aluminium.............................if I'm wrong, I'll apologise in advance but............

Regards.

Dave.
