First let's identify the patterns so we are all on the same page.
I always believed the " First pattern" was the cover used with NO foliage slits.
The "second pattern" was the cover WITH foliage slits AND BUTTON HOLES
The "third Pattern" was the cover WITH foliage slits, but WITHOUT button holes.
Then came the 1952 Blue Anchor Overall covers, which had foliage slits, no button holes.
These are simplest to pick out even in photos on a helmet because of the USMC EGA stamp with one riband.
I have also believed that the Dark EGA stamp ( no riband) was applied to SURPLUS WW2 produced covers, both first, 2nd and 3rd pattern ( as described above).
These covers are most commonly seen POST WAR up to Vietnam...
That's what I have come to discern from my years of collecting. The photos I see from Tarawa are without foliage slits (unless I am wrong, and now I will go back and double check) but early use of cammo ( Cape Gloucester) I always believed to be the non-foliage slit type covers. Also I am sure there was a point where the styles blended as circulation of more covers increased ( hence foliage slits from Tarawa pics ( above)... Never really gave it the depth of thought...
