There is 1/450 USN railing from Eduard. I may have some if you do not find any.
The GMM 500 naval set may work as well.
It is best to use smaller scale pe on a ship if there is no pe available as in 1/480 or 1/450.
The 1/426 Arizona set may also work as it has a number of items to use.
Note you can use solid borders on a pe fret to make much thinner gun tub walls and splinter shields. Looks much nicer than thick castings.
I a building and reworking a Fujimi 1/450 Haruna and note the GMM 1/500 IJN BB set matches perfectly.
