Original Item: Only One Available. The U.S. WWII M-1 helmet was only produced from 1941 to 1945. The first production batch resulted with over 323,510 M-1 helmets before the start of the American involvement in the war. This helmet is stamped with lot and lift number 103A, which indicates the approximate manufacture date of March - April 1942, a year and a half before the transition to swivel bales.

The Ordnance Department selected McCord Radiator and Manufacturing Company of Detroit Michigan to produce the steel M1 helmet bodies. These bodies were made from a single piece of Hadfield Manganese steel that was produced by the Carnegie-Illinois & Sharon Steel Corporations. Each completed raw M-1 helmet shell weighed 2.25 lbs each.

The early M-1 helmet shells had a set of fixed chinstrap loops called "bales" and a stainless steel rim. These rims were both rust resistant and had "non-magnetic qualities" that reduced the chance of error readings when placed around certain sensitive equipment (such as a compass). This helmet is a fine example and still retains many of its original WW2 parts and the shell has all original "corked" grain paint. It does look to have seen a good amount of wear but no intentional abuse. The chinstrap is still present with the correct early war brass hardware.

The helmet is a striking Navy Haze Gray color and is in a remarkably good condition. On the exterior, there are several name stamps that read "MICKELSON W. L." Unfortunately, despite spending a considerable amount of time researching the name, we couldn't find any concrete information regarding his service in the US Navy during WWII. The helmet is adorned with multiple chips in various areas, indicating its usage, and has a noticeable dent on the top. Despite these signs of wear, the overall appearance of the helmet is quite impressive, and it's clear that it was well taken care of.

The liner is correct high pressure WWII issue and stamped with a W for the Westinghouse Electric Co Manufactured in Pittsburgh, Pennsylvania this "high pressure" manufactured M-1 helmet liner is identified by an embossed "W" in the crown (which is still Westinghouse's logo to this day). Westinghouse was the largest M-1 helmet liner producer and had two production divisions; Micarta and Bryant Electric. The Micarta Division produced about 13,000,000 M-1 helmet liners and the Bryant Electric Division about 10,000,000. Westinghouse Electric Company started M-1 helmet liner delivery in May 1942.

Westinghouse did have a contract to produce airborne liners and converted an unknown amount to airborne configuration. Westinghouse discontinued production around August 17, 1945 when the war ended.

This true US WWII M-1 helmet liner can be identified through the frontal eyelet hole. Other correct WW2 features include cotton herringbone twill (HBT) cloth suspension. This HBT suspension is held tightly within the M-1 helmet liner by rivets and a series of triangular "A" washers. The three upper suspension bands are joined together with a shoestring. This way the wearer could adjust the fit. The sweatband is present and still in solid condition with areas of wear. The liner chinstrap is present with blackened hardware and is presented in solid condition.

These helmets have become increasingly difficult to find in recent years, especially genuine WW2 issue liners with the correct HBT straps. A lovely example with some great research potential, almost certainly to appreciate in value year after year!

M1 Helmet
The M1 helmet is a combat helmet that was used by the U.S. military from World War II until 1985, when it was succeeded by the PASGT helmet. The M1 helmet has become an icon of the US military, with its design inspiring other militaries around the world.

Over 22 million U.S. M1 steel helmets were manufactured through September 1945. Production was done by McCord Radiator and Manufacturing Company and Schlueter Manufacturing Company; the former developed a method to create an almost eighteen-centimeter deep bowl in a single pressing, which was an engineering milestone at the time.

In 1944, the stainless steel helmet rim with a seam at the front was replaced by a manganese steel rim with a rear seam, as well as the helmet bails being changed from a fixed, welded version to a swivel model in 1942, along with slight alterations to the shaping of the side brim. Further M1 helmets were manufactured for the Korean War.

Production continued during the Cold War era with periodic improvements; in 1955 a grommet in the front of the liner was deleted, in 1964 the liner construction was changed to laminated nylon and a new chinstrap design was introduced in 1975. The final contract for US M1 helmets was placed in 1976. The M1 was phased out of US service during the 1980s in favor of the PASGT helmet, which offered increased ergonomics and ballistic protection.

Following World War II, the M1 helmet was widely adopted or copied by numerous other countries and its distinctive shape was adopted as the NATO standard. Postwar analysis of wartime casualty figures by the US Army Operations Research Office found that 54 percent of hits to the M1 helmet failed to penetrate, and estimated that 70,000 men had been saved from death or injury by wearing it.
