To that end, I added the two lookout stations near the top of the masts as well as the two spotlight stations at the bottom that are called out in Step 12. The whole reason I had waited to fix the masts in position was to ensure that I could get both of those features aligned properly, no easy task as they stick out at different angles relative to each other and different features on the rest of the superstructure.
I had to modify the bases for the searchlights slightly by thinning the rear portion somewhat so they would fit the slots in the mast legs properly. I also drilled out the solid faces of the searchlights so they would have more depth to their finish. A bit of Silver enamel paint did the trick for their reflective inner faces. The railings called out in Step 13 that protect their little platforms were very tricky to shape properly as the two platforms aren't quite the same shape and the railings also interact with the mast legs. I had shaped the railings before I added the platforms to the legs and the railings were gently slipped into position and then glued down with CA. Again, this is a maneuver that would've been virtually impossible IMHO if the superstructure had already been attached to the deck as the instructions would have you do it.
For good measure, I also added the railings and floater net basket PE parts that are called out in Step 13. I had deliberately waited a while to add them as they sit in a spot that gets a lot of handling while adding the other stuff with the superstructure levels. Last but not least, I test fit the superstructure once more on the hull, adjusted the height of the tripod legs slightly, and then secured the legs into a permanent position with the little platform E37 from Step 10. The starboard leg needed a little coaxing to pull into the correct alignment so some patient use of finger pressure was called for to keep it in place until the glue grabbed enough to do the job. The three little sections of railing that are called out in Step 16 were added to top it off.
Whew! After all that, I've finally completed all the stuff called for in the first 16 steps of the instructions. Before I had committed to the tripod masts getting locked into place, I had knocked together the main part of the fighting top so I could check one more time that the legs were all lining up properly. Here's how it will look with the hull later on when the top is added.
Still a lot more to do on this one, I'm still debating on just how far to go with the fighting top before installing it as it's got a lot of complicated PE and snaggable parts that go into its assembly. Have to give it some thought vs. the other areas of the ship that still need a lot of detail attention.
