can't measure it exactly). Definitely bigger than 1/4". The tower lives
in a very salty, island climate.

Read where? I haven't heard of it - especially when it comes to
towers.
All USA crank-ups that I know of use common 7x19" galvanized. Since
the original is unidentified, I'd suggest following the overwhelming use on
Ameriacan crank-ups and use the 7x19 of whatever size you need.

Only if it's going to be installed outdoors. (That's a joke, son.) Of
course use galvanized.

would be best if I can't find the 6x19 LC.
Yes. The 6x19 might be an English standard. It sure isn't the US
standard.
