What color is this Carryall?

Trying to figure out what color this Carryall is. I contacted the owner and "she", yes she... was rather unclear. She said it was late war Semi-gloss, but I ordered a spray can of it and tested it and it seems way too "mustard" or brown. Its not as "dark" as I am looking for. I am trying to find an Olive Drab that is border line black... any suggestions would be greatly appreciated!

Looks like 24087 to me, same color I painted my M37 with. I used the Gillepsie brand without the hardener.

Thanks Frank! I ordered a spray cab of a few different colors of GCI stuff last night after posting that. This way I can really get down to what color I want to go with. I am thinking I am going as dark of an OD as I can get to lean it towards a civilian look but not quite end up there. What does the addition of hardener do? I'm not very "paint" literate.
