Pro Circuit triple clamp color

Try this place, I know they do some parts for pro circuit

Looks to be regular bronze. If you send them the top clamp, they should be able to match it. 

I've never had them anodize anything for me but I have talked to them in the past about it after having a bad experience at another anodizer. With that being said I plan on using them the next time I need something anodized, when I talked to them on the phone they knew their stuff. They do a lot of anodizing for the custom boating industry also.

Note that you are going to lose the Procircuit logo when you re-anodize it although if they are doing Procircuits anodizing they might be able to re-etch the logo?
