Todays work.. lots of inefficient mask blemishes to fix. Took the masking tape off the tail fin to have the paint come with it, seems to be a theme in this GB!
I think the color you need is something close to Aircraft Insignia Blue, ANA 605: FS 35044
(Model Master 1719/4742, Humbrol 189, Tamiya Royal Blue X03 - no polly scale equivalent)
It's sort of a dark blue with perhaps a touch of dark grey mixed in. Not good at describing it.
Btw, according to a review I've read of this kit on modellingmadness.com by Tim Mansfield, White 301 is not a TBF-1 but rather a TBM-3. You can find a picture of white 301 in "Avenger at War" page 87. White 301 was assigned to VT-84 USS Bunker Hill 1945
Thanks for the info guys, will reconsider and order the 'real' dark blue. Looking at it, the blue looks way off and like a picture of this crappy hellcat model I always see at the LHS which was used for cover art (same dark blue as mine).
Rather than get a new blue, you could try mixing a spot of black or grey into what you have. Actually I'd lean toward mostly grey with a spot of blue. I wouldn't go too dark as these Pacific machines bleached quite a bit in the sun.
