This would have been a perfect addition for the Jim Sullivan group build we have going on right now. You are always welcome to join us there if you wish.
The questions about the interior are good ones. Originally these were finished in the aluminum lacquer paint, however, as they went through overhauls, the interiors were painted using Green as mentioned above. There's a great source of information on a website that was ran by Lynn Ritger. I'll see if I can find it and post up a link to it. he covers all of the Bureau Numbers and eventual fates. It should help you with the instruction's misprints on the history part.
Here are some excellent Pre War color photos that show the shade of green that was used. Several years ago, as part of our Midway Group build, I built up one of the old 1/48 scale Monogram TBD's in my stash, and I did a lot of online digging on the subject.
One thing I thought was incorrect about the color call outs was in reference to the on board fire extinguisher that was mounted in the middle cockpit. They were a polished brass color, and not a red. Red is a color that was introduced on most of the fire extinguishers a little later on. There were some that were painted red during this era, mainly the CO2 types, but not the one I'm talking about.
I have included a photo showing you what it should look like. This is a picture of the real thing.
Hope this helps.
I'm a retired firefighter, and I know a little about extinguishers too.
