Scrapdaddy, does your M37 have the factory dash placques?
319 is actually not the correct color. The original factory color for an M37 built in 1951 is 23070, which Rapco and others carry. I'm painting mine in that color. It is a slightly darker semi-gloss version of 319. It did not last long, and most M37s painted in 23070 wound up being painted with 24087.
The problem with the current 24087 is that it is not the correct color. A change was made and it was known as 24087X, intended for helicoptors. The original 24087 color is actually 24084, but I have not found a source for it. The incorrect 24087 has a brownish tint to it, while the proper 24087 (24084) definitely lacks the brownish tint.
You can see a comparison of 23070 and 24084 here:

Note that 24087 no longer appears in the current official milspec paint chart. Helicoptors are no longer painted with this color.
I have verified 23070 as being correct, because I disassembled some parts from my M37 that have never been taken apart. They've been sealed by gaskets and original white grease seal, keeping out light, moisture and air. I oversprayed half this part with Rapco 23070 and the colors were so close I could not find the paint line.
My M37 has been repainted several times with darker greens, all of which are variations of 24084. The colors varied in the 1950s. The engine compartment, though, was never repainted, and remains 23070.
If you want to try a spray can of 23070, they are $6.50 plus shipping from
