USMC 2-Cell Grenade Pouch/Carrier Addendum

Was looking at some older threads regarding the title topic and this one seemed to be the most extensive one:

Wanted to post additional photos from some recent observations, but realized the above ink was in the history file,  thus could not attach them to it. So, decided to start a new thread and add the pics here. The first two photos show a "U.S.M.C." branded, 2-pocket pouch as discussed in the initial link posting (#1). The third photo is another example but in khaki web. It has the brass M1910 belt hook.  I noted the "period" after the "U" is weak on both examples.  The last two photos are interesting as it appears to be earlier production like photo #3 with primarily tan webbing and having a non-blackened, brass, M1910 belt hook. I thought the darkened area on the left side of the top pouch flap was a stain. However, one can see it appears to be a ink stamp marking with contract or inventory numbers visible (particularly the last four digits).
