Sorry I've worked on computer systems professionally for over 30 years. I'm retired now and still spend way to much time in front of the monitor
when I should be working on my boat.
I know a really knowledgeable surveyor
. I'll give him a call and see what he thinks. Only problem is I never know when he'll pick up. I talked to him about refitting with bronze over stainless and he felt that so little bronze is being used and made today that you have no idea of it provenance and would need to have every piece tested for the quality of the material.

I did a cursory search on Brion's website and came up with this:

First, are you certain that it is bronze? Many allegedly bronze fittings are actually brass, including those made of "naval bronze" and "manganese bronze."
Second, while bronze is much more fatigue-resistant than stainless, it will harden in time. If this is an old fitting, used regularly, it might need to be annealed.
Third, bronze is less noble than stainless, so a prime place to check for galvanic action is under fasteners.
Time to finish my morning coffee. :-)
Good luck on your quest.
