Thanks a ton Lasher...I sincerely appreciate the info.
One last question, do you happen to recall which particular style of camo helmet cover that most Marines were being issued during that time (photos below...#1 Mitchell pattern, #2 USMC 3rd pattern, #3 USMC mosquito net cover)? Based on photos it looks like the USMC was using four different covers at this time (including the solid OD cover) and I'm not sure which one was the most issued. I have always assumed that the Mitchell covers weren't widely used yet as there had only been one production run of Mitchell covers for the USMC (in 1959) up to that point. All the other Mitchell cover production contracts prior to 1965 were Army if I remember correctly.
Thanks again for your input.
#1. Mitchell pattern
#2. USMC 3rd pattern
#3. USMC mosquito net cover
somewhere i have a photo of me in my helmet, it's in black and white so it's a tough call. we didn't have chin straps like #1, so i'm going with #2 but much more faded LOL, altho it seems there was more green in the pattern. if #1 had a chin strap like 2 & 3 i would have said #1. i loathed my helmet so only paid attention to it when i needed it. i suspect it's the cause of neck vertebra problems i have, sucker was heavy and the green machine had a 1 size fits all in the liners, having a giant gourd was a plus, not having a giant gourd resulted in lots of bounce and headaches. if i find the photo i'll see what if any light it would shed on the question
