Very nice. I like your battery tube inner wrap. Your mod reminds me of mods gone by and rarely posted up today. Thanks for taking the time to post it up.
I wonder how well the anodising would bake?
Hmm… after seeing the innards of yours I’m inclined to follow suit and do some tweaking. Nice looking head, too. Did you rub off the coating and will it patina now?
It looks like we are looking at nickel. All Noctigons are very thin coated gold on the outside, nickel underneath to help the with the gold bonding, and then the solid copper under the nickel. Around the indentations, you can see all 3 layers.
The gold can be removed practically waving super fine grit sandpaper over it, while the nickel takes a little bit of rubbing. I've sanded down many a Noctigons over the years.
