The one I picked up in Panama had a set of white and red oil/ solvent bottles on the right side and this wad of cotton material stuffed in the left. I have a second set of bottles that came from another pouch. Bottles are marked I (white bottle /yellow lid) and II for the colored (red or blue) bottle. I've seen pics of similar NK bottles with a star on the lid where these have concentric circles. I'm not sure but I believe these are NK issue oil bottles that are a sterile export type. The NK Type 68 AK's we encountered there were also lacking identifying markings other then serial numbers and selector markings (1 and the infinity symbol).
I know this is an old thread, but maybe someone has some new information regarding what the 2 front pockets on these NK pouches were used for. They are round pockets, at least on the Type 68 pouches, so were they originally for grenades or oil bottles? Weird to make them round shape for rectangular oil bottles.
