:waves to the new guy:
Dunno if it's of use, but there's a lot of nice pics in this thread that'll likely give you an idea.
Beyond that, I'd imagine that if it's aluminum it gets cleaned (mabe polished a bit) and left nekkind/uncoated, and if it's tinwork, it's either a shade of gloss gray (SPICA stuff) or gloss black (carb'd stuff), but I'm not a 'proven source' on that stuff so doublecheck please
Still, they're definitely not gold.
