How To Identify A Helmet Heat Stamp: Korea - Vietnam

[@chaplainleggitt]

Good video. I was the quality control person for the 1968 & 1969 Vietnam era M-1 helmets (#6521) made by Dana Corporation at their Trenton, Michigan, factory. When I worked there both the materials and the manufacturing process were classified. From what I understand that info is now in the public domain. I can explain why some helmets that should have a back seam, have a front seam, and vice versa. I can also explain why the heat number can be anywhere on the helmet, inside or out.

[@jimmymarsh2489]

I would love to hear more about your job. You should make a video for us. I love the M1 helmets, and I love hearing about them. Thank you for sharing sir

Thank you John boy ,once again you have helped me to identify the m 1 pot I just aquired as an RJ stampings , right down to the stainless steel rim and tape residue. You are a veritable cornucopia of knowledge , and a true patriot, God bless you and your family !

@@JonBoyMilitaria I found a descrepency with RJ stampings I always thought they made helmets from 1971 to 77, however if you look up their business records it says they Incorporated in 1977 to 84, also do you know of there is a book on m 1 pots that includes all wars, and a makers list.

Is the liner in backwards? It sounds like a silly question but I have seen helmets with liners in backwards and the liners rim sticks out beyond the edge of the helmet.

Hello man, really enjoyed the video. U got my sub. I have a question tho: From what time is my M1 helmet? Its back seam and the stamp says either "M46D" or "1146D", but without a space in between the M and the number? (If its an M, then the line in the middle got scratched or sth) The printed stamp in the webbing is barely readable, but probably says 1951/1963 (?) Ive gotten my hands on this particular M1 helmet, that had been laying around in a barn in southern Germany for decades now. Full helmet, including outher shell and inner one. Chinstraps made of leather broke after just touching them. Greetings from Germany :) Edit: Whats also interesting, is that the paint at the front is scratched off and there are two vertical welding points there, so something was welded on there, what could it be?

[@JonBoyMilitaria]

The 2 vertical welds were probably where captain bars where. If the heat stamp does start with the letter M then it was made in 1951 by McCord.

In 1969 and 1970 I was THE (yep, there was only one.) quality control person for the M-1, 6521 Dana Corporation manufactured army helmet. The Federal government thought the less people involved in this TOP SECRET project the better. My first day on the job I had to sign a Federal government non-disclosure form. That form has never been rescinded so I really don’t know if I’m still bound by any of it today. I can say with confidence that there are secrets still today about the helmet that the general public knows nothing about. When I worked on the helmet project at Dana I always carried a set of blue prints for the helmet. Each page was rubber stamped TOP SECRET. I also was one of the few people who knew the formula for the alloy. There are secrets about those helmets (especially about the alloy) that if I were to tell you, you would say that I must be making it up. So now 50 years later I’m still hesitant to disclose everything I know about the M-1 Vietnam era helmet.

Good stuff, I have a question. Not sure what you were saying about the Korea McCord helmets being repurposed. Were Korea helmets used in Vietnam? I have a McCord helmet with the rear seam, not stainless steel, I'm trying to date it but there is so much confusing information everywhere. I looked on a sight Top Pots which had the following info; " In October 1944 the rim material changed from stainless to the same steel that the helmets were made from (Hadfield Maganese). Evidently, for some unknown reason, at the same time, the weld seam of the rim also migrated to the rear. The total production of WWII M-1 helmet shells reached over 22,000,000 by August 1945. M-1 helmet production ceased just days after the war ended. Noted: M-1 helmet shell production would not begin again until March 1951 because of the Korean War". You appear to have real good knowledge on the subject, can you help me?

[@JonBoyMilitaria]

If you can locate the heat stamp that would be good. There is a chance that your helmet was made in late 1944 - 1945. But If the heat stamp starts with the letter M or starts with an MW then it was made in 1951. But Ww2 helmets, gear, weapons, supplies etc were used in Korea and Vietnam also just like a lot of left over WW1 stuff was used at the beginning of WW2.

[@BackPackFilmsFl]

@@JonBoyMilitaria The heat stamp is M 310, or the zero is a nine but I'm 97% sure it is a zero. It's interesting cause there are two names on the helmet, one with extremely old large masking tape, and another name x2 one inside in faded pin and again outside scratched in. I have what I think is a mid 60's liner and a 76 cover.

Hello from Germany, I have an m1 helmet with the stamp number 8561 (big) can u tell me something about it? And my second is ingersoll I - 250(4) I think its number 4 I would like to know the produce time LG Thomas

[@JonBoyMilitaria]

Hey Thomas, the 8561 with Big Numbers is more than likely ans Ingersoll also. The 1 or I before the numbers might be faint or worn out over time. Ingersoll made helmets from 1965 - 1968.

My M1 Helmet shell has its numbers painted over and is very difficult to see. Besides this, the numbers appear to be very small and upside down. I also have a marking inside that reads JLA in all caps, at first i thought is was initials, but then i saw somebody had a helmet with intials that was related to the Belgian clones. Any help would be greatly appreciated, good vid!

Small numbers upside down makes me think a Vietnam era Parrish

Thanks a whole lot for these videos! As a noobie in the helmet collecting scene I've found American helmets to be the most complicated, surprising considering so little variation between them exists when compared to the various changes in german helmets. This has certainly improved my chances of making educated purchases in the future :)

The model (M1), is not exactly the same over time, and in the different wars in which it was used ??? Do they have differences between them ?? I do not speak the English language, and I could not intervene aurally, so interesting video. Use the google translator to write. Many thanks! CORDIAL GREETING FRIEND !!

[@JonBoyMilitaria]

The M1 helmets started being produced in 1941. They started out with a front seam and fixed bales. In October 1943 the bales were switched to swivels and then around October 1944 the seam was moved to the rear. The M1s in this video are the post World War 2 ones. In this video, I am going over how to determine what era the M1 was produced and also showing examples of the companies that produced them as well. I hope this helps. Thank you for watching.

[@zpadventures7440]

Not sure. So the helmet is a rear seam? The heat stamp on Vietnam era helmets could be just about anywhere inside the helmet. It could even be upside down. I usually use a magnifying glass and a small LED flashlight to see heat stamps. You could also use the pencil and paper trick, or use a piece of chalk and go over the heat stamp area.

I'm sure I don't' know what I'm talking about, but I always thought there was a shape difference between WWII and Vietnam helmets. WWII era helmet (to me) seem to have a higher and more rounded '"forehead." If that makes sense. Going backwards from the front rim, the WWII version had a steeper front, while the Vietnam helmet was more sloped to the rear. Just the way it looked to my eye. I wore the helmet during Vietnam, and never heard it called the M1... it was just a "steel pot" or just "pot." Most draftees wouldn't know what an "M1" referred too, unless the Garand. I would have never thought people would one day pay so much attention to the trivia of a steel pot.
