denfly Posted December 26, 2018 Share #126 Posted December 26, 2018 Would this heat stamp mark this shell as having been manufactured by ingersoll? The shell itself came with Vietnam hardware and a 1972 dated P64 liner. Yes, that is an Ingersoll helmet used during the Vietnam era and after.

Phileah Posted February 23, 2019 Share #127 Posted February 23, 2019 Since I asked the question about the blue ink stamps I have picked up 2 more that also have a 4 digit lot number stamped into the metal. One has a -42- ink stamp and 1421 stamped into the steel. The second has -10- ink stamp and either 1521 or 1527 stamped into the metal. Anyone know the manufacturer for these lot numbers?

Phileah Posted February 23, 2019 Share #128 Posted February 23, 2019 Correction to the lot number on one of the ink stamped helmets I just mentioned. Ink stamp -10- with lot number 5121 or 5127. I also just got one with lot number 7492. Could I presume this is a Dana? Link to comment Share on other sites More sharing options...
Phileah Posted March 9, 2019 Share #129 Posted March 9, 2019 I now have more ink stamped M1's with 4 digit numbers also stamped into the metal. All these with a 3, 5, 6 0r 9 appear to have the same font style as the Dana listed helmets on the forum. These numbers are more open at the curved ends where RJ's numbers are more curved and closed in. My opinion would be that ink stamps are on Dana Parish helmets.

These numbers are more open at the curved ends where RJ's numbers are more curved and closed in. My opinion would be that ink stamps are on Dana Parish helmets. Parish/Dana often used blue ink stamps. The meaning of these stamps I am not sure... Possibly indicating specific helmets within the lot, or specific groups within a steel lot. Those are just guesses, until someone finds documentation stating what the stamps mean, we will not know. Link to comment Share on other sites More sharing options...
denfly Posted March 23, 2019 Share #131 Posted March 23, 2019 Possibly quality control stamps to see if the helmet is free of cracks as often seen on a number of M1's in the past? Link to comment Share on other sites More sharing options...
Corpsman_1941 Posted April 14, 2019 Share #132 Posted April 14, 2019 What do you think about this one? Post war M1 with strange number-only one digit between M and A. Very early 1950s manufacture or error is heat stamp? Link to comment Share on other sites More sharing options...
Justin Posted April 14, 2019 Share #133 Posted April 14, 2019 Perhaps are early production McCord. Looks nice. How's the paint/texture? Does it have chinstrap? Link to comment Share on other sites More sharing options...
denfly Posted April 16, 2019 Share #134 Posted April 16, 2019 Looks like an early Korean war era M-1. I can make out the dash right on the paint line towards the top. A single digit 1950's M-1. Link to comment Share on other sites More sharing options...

denfly Posted September 7, 2020 Share #147 Posted September 7, 2020 On 12/11/2015 at 9:36 PM, usmc grunt said: Three digit heat stamps on rear seam M-1 helmets that begin with 4, 5, 6 or 7 indicate the manufacturer as R.J. Stampings of Montreal, Quebec, Canada. These helmets are typically fitted with the post Vietnam cotton / nylon chinstrap that has a chin cup and attaches to the bales with removable clips. These are the only helmets that were shipped with combination duct tape / Styrofoam padding located near the bales (see photo). If you have an M-1 helmet with a 3 digit heat stamp and a white residue located near each bail, you have an R.J. Stampings helmet. Actual heat stamps found on R.J. Stampings helmets include 404, 501, 502, 503, 504, 507, 531, 541, 601, 602, 603, 608, 609, 623, 626, 629, 608, 609, 632, 635, 692, 693, 701, 702, 723, 734 Just viewed one on facebook that has 506 heat stamp.

Sgt127 Posted October 17, 2020 Share #150 Posted October 17, 2020 Greetings all. Dug through My stuff. Mind you, I got these in the late 60’s early 70’s and wore them when I played army. Both have rear seams. Swivel bails. Dark Olive one looks like M-131A The lighter Green one just has 6. Ive got liners for both but, as a kid, I mixed and matched. May have had other liners. No idea what went with what. Anybody want to guess on date and maker? Thank you. Link to comment Share on other sites More sharing options...
