OK, so I found the Aervoe product page: https://aervoe.com/product/military-vehicle-and-recreation-camouflage-paint/
It lists 4 different colors as "Olive Drab". Their part numbers are 24084, 24087, 34087 and 34088. Interestingly, searching on the Aervoe website for "987A" brings you to the above product page, where there is no mention of 987A at all.
Brownells lists the manufacturer part number of what I bought as 987A, which of course is not anything that Aervoe lists.
Guessing by Aervoe's swatches, I think I might have the 34087, and 34088 might be a much better match. But that is one "guess" and two more "might"s than I'd like. I'm hoping that when I get home tonight I can find a number on the can that will tell me which one I actually have and is shown in my photo.
