Which it was, ex-factory, for the -1 and -2. It is unclear when/if before -3 production Vought changed over to whatever cockpit green they used. There had been complaints about glare in the cockpit due to the aluminum finish. If you look at the famous Life picture of the prewar full color TBDs on deck, and look at the visible cockpit on 6-T-16, also aluminum ex-factory, it has been repainted in a green. I also remember hearing recently that some aircraft had the upper cockpits painted blue-gray, like the exterior, at some point after they went to camouflage, December 1940.

Here's another link to an article about interior colors and the various uses of paints with dated memos from the Army and Navy that was also written by Dana Bell.

I zeroed in on the sections that would have applied to your Vindicator. This is literally copied word for word from his article, in hopes that this may help you with your build.

19 Jan 1940 Navy Spec SR-15C identifies “cockpit green” color as “dull bronze green lacquer, Army color #9.”

28 Nov 1940 Navy memo notes that Spec L-12a “...has been revised to replace the current Dull Bronze Green...with [Dark Green #30] lacquer...”

17 Dec 1940 Army memo accepts Dull Dark Green for cockpits and anti-glare.

01 Feb 1941 Army memo cancels list of approved oil base metal primers; they are replaced by zinc chromate primer.

03 Feb 1942 To conserve aluminum pigment, Navy memo recommends tinting second coat of zinc chromate primer with Indian Red, lampblack, or other suitable indicator. Light gray can be used on fabric surfaces where aluminum dope has been used.

31 Aug 1942 Curtiss-Wright memo reports Berry Brother 174-G-13 to be used as “Curtiss Cockpit Green.”

10 Sep 1942 Navy memo proposes to replace dull dark green with new green standard for cockpits. Proposed color can be procured as lacquer, or made from zinc chromate primer, tinted with black pigment.

It looks like Dull Dark Green was proposed to be replaced with a "New" green standard for cockpits on Sept 10, 1942...

Hope this helps you with your research Chuck.

But in the end it is your plane and you should build it as you see fit. Either way would really look nice...

Working on the rear gunner/navigator compartment. A little bit more complicated and careful in building the side panels front and rear avionic racks. Slow going as being careful not to misalign any of the components here, test fitting each step as it is very tight here when closing the fuselage halves. Also adding the PE bits, painting and detailing the various boxes on each panel. A little wash on the rear compartment floor to enhance the details. Added the belts to the gunners seat pan. After getting the various details painted it was time to start assembling, as mentioned earlier, very careful as the locating point to each part is not exactly clear in the instruction sheet. Already had a bad feeling in getting the rear seat installed. It was quite tedious here. I had to walk away after trying to manipulate the seat into place. But finally got it installed whew! Not perfect but it will suffice. With that I call it a day for this one. More to follow

Happy Easter Louis, yeah AM did an amazing job in research in getting as much detail in plastic without over engineering. Though the parts are detailed and pretty close to scale, something you would get in resin difficult to create in plastic. Still you have to take your time just like in the Dauntless, the parts are flimsy which is not a critique, but just being aware of being careful in assembly and test fitting. Especially in locating the parts in the correct position. Important when it is time to get all the sub-assemblies installed.

wow - coming along nicely!

This one looks pretty complicated ! (and you are doing a great job with it too ! ) They sure have packed a ton of details into a tiny package... Look great Chuck.

This update I start with adding the tail planes. These do have a good fit once they are installed. Next we build the wings up before the task of installing them to the fuselage. There are parts in the kit to cut them if you wish to fold them. I decided to build this with them in flight position. First installing the wing mounted machine guns on the leading edge. Next carefully placing the wing spar in place before cementing it to the lower wing half. A slight warp with the lower wing, the wing spar took care of this nicely. The fit of the wing to the fuselage is not quite as positive compared to the Mono Devastator, had to play with it a bit to get it to sit as it should, and even then it wasn't quite as it should be. Since it did try my patience a bit, will let it sit overnight and work on the engine next. More to follow
