pawtwo Posted September 25, 2018 Share #1 Posted September 25, 2018 Hello, Can anyone give me an idea when black plastic cap for plastic 1QT canteen was introduced? I know that very first M1 NBC caps were made of OD green plastic, then at some point they changed color to black, to made them easier to distinguish. I've never found when they made first caps in black but these were made black as late as 1986 and still used during desert storm, in 90s and sometimes even later.

GUDMAR1975 Posted September 25, 2018 Share #2 Posted September 25, 2018 I think you are correct on time but perhaps out of sequence on the color. The first caps were black and issued separately if I remember corectly. Later caps were green and the canteens were issued with the NBC cap on.

pawtwo Posted September 25, 2018 Author Share #4 Posted September 25, 2018 MSA make them OD green in 60s. I believe black ones were introduced a bit later. Link to comment Share on other sites More sharing options...
Cap Camouflage Pattern I Posted September 26, 2018 Share #5 Posted September 26, 2018 Interesting, didn't know about those 60s green ones. But as far as I can tell the black ones were superceded by green ones. So I guess the order goes green black green. IIRC the later green ones have a thicker strap holding the nbc cap on to the cap than the black ones. I will confirm when I get home. What do the early green ones look like?

ECHOROMEO Posted October 7, 2018 Share #6 Posted October 7, 2018 Does anyone know when the switch from black to green M1 caps happened? Late 80's? Link to comment Share on other sites More sharing options...
pawtwo Posted October 7, 2018 Author Share #7 Posted October 7, 2018 I had few new black caps in original plastic bags with 1986 contracts (DLA100-86-C-4238), while MIL-C-51278D dated 30 June 1987 says that M1 cap should be OD 34087. Cap still had one piece construction where main part and top closure was made as one mold. Specification says that strap holding closure to the cap should withstand 25 000 openings what I think it's crazy as you can damage it really fast. Previous version of specification was MIL-C-51278C from 28 March 1983 but not all full revisions of specifications changes overall design of an item.

ECHOROMEO Posted October 8, 2018 Share #8 Posted October 8, 2018 Thank you. Do you also happen to know when they switched from the one piece to the two piece design? Link to comment Share on other sites More sharing options...
Cap Camouflage Pattern I Posted October 8, 2018 Share #9 Posted October 8, 2018 Thank you. Do you also happen to know when they switched from the one piece to the two piece design? I thought that occurred along with the change to green. At least I have not seen any green ones in the earlier style or black ones in that style.

ECHOROMEO Posted October 8, 2018 Share #10 Posted October 8, 2018 They did come in green with the one piece design, I've got one. (not my photo) Link to comment Share on other sites More sharing options...
Cap Camouflage Pattern I Posted October 8, 2018 Share #11 Posted October 8, 2018 Very cool, never seen that before! Learn something new everyday! I wonder if this is before or after the black ones. Link to comment Share on other sites More sharing options...
ECHOROMEO Posted October 10, 2018 Share #12 Posted October 10, 2018 Pawtwo mentioned it above, when the color was changed in 1987 to OD green it still retained the one piece design. So does anybody know when it was updated to the two piece design? I'd guess sometime in the 90's. Link to comment Share on other sites More sharing options...
