I have 4 total. Can get at all of them, and have the good old wooden pegs tied close by each, but I'd prefer not to go down that path.

colour test is the most obvious, the pink showing dezincification. If it is not too much of a mission take a sea cock off and check condition of the threads.
Given the age of your yacht they should be old Chatfield or Metabronze fittings, made right here in NZ.
By the way how many people know that many boats, especially those built in NZ, have a mismatch of threads between their skin fittings and sea cock valves?
Skin fittings always have a parallel thread whilst valves typically have a tapered thread. The latest True Design valves made for sea cock have parallel threads whereas the Marelon and Hansen plastic valves, and the old bronze gate valves used in days gone by were mostly tapered threads.
