Any interest in testing this on the parts I am looking for?  I'll provide material and artwork!!

Thanks for your consideration, Bryan

Thanks for the offer DJ, I appreciate that.

I will just order a few phosphor bronze sheets and build a CuCl solution, and get with the program to see what it takes.

Thanks,

Roger

I suspect the process is the same, along with undercutting etc,
although the chemistry might have to change. Brass works with PCB
techniques because the brass reacts to etchant the same as copper
does.

Bronze is still a copper alloy, it might react the same too. If you
want to mail me a small piece(like, 0.5" sq or smaller, doesn't take
much), I can dip it in the CuCl etchant and see what it does.
