I'll send you a more detailed list of what seemed important to me.
First, all that impressive deck piping is bogus. The major pipes from the loading hatches are in fact just the 4" hold vent pipes that were ganged and sent up the masts. Replacing those with thin wire is a bid plus.
The hold hatches are ok, but all of those other little bumps are supposed to represent the vertical shaft and hand wheels of the valves connecting the holds to the unloading piping. I tried to find tiny little hand wheels with no luck. N scale were too big. One thought was a straight pin and its head.
I spent a bunch of time carving off detail- in hindsight it would have been a lot easier to make a new deck.
Other more minor stuff- a new bridge front that had camber across the face of the spray rails, even though the decks behind them stayed flat, and round bridge windows. Actually was not hard to make up. The real thing is pretty dodgy anyways so was not too neat.
I replaced the catwalk as the railings had to go, but that was kind of a pain.
Add GMMs excellent 1/400 us navy set which also does Pine Island and you have a winner.
