Looks like a good color for Steam Punk. I don’t really like it, though, personally. I prefer shiny real metals and/or flat black or the occasional nice color (blue,red mostly). The “gold” “copper” “bronze” and other colors of “metal” are not for me.
Brass with the right patina method would give a similar result.
I tried vinegar fumes that give some dark coloring with a green hint. Scrub it with some steel wool to get rid of it and you have a sweet aged brass finish.
The bronze effect could be achieved with gun bluing maybe, and some stonewashing after that ?
