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 229B, which indicates a manufacture date of 1942. The front of this example is stenciled with USN on both the shell and liner, which is often associated with the Seabees.

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 all of its original WW2 parts and the shell has all original "corked" grain paint with front seam and fixed bails. It did see service, with both the shell and liner stenciled to the front with USN in white. The interior of the shell and liner are stenciled with the initials S.G.M., and the sweatband has the name PFC MACCARONIO(?) which is a great research opportunity.

The Liner, which is one of the rare examples made by INLAND, was also painted with USN on the front. The Liner suspension is OD#3 (Khaki) fastened into the liner shell the means of Zinc-Coated “A”-Washers. The liner is complete with original sweatband and nape strap. The suspension is worn as shown, but overall does not detract from the outward appearance or displayability of the helmet itself.

This is a fantastic painted helmet with tons of research potential. Comes ready for further research and display!

Seabee
United States Naval Construction Battalions, better known as the Navy Seabees, form the U.S. Naval Construction Forces (NCF). The Seabee nickname is a heterograph of the initial letters "CB" from the words "Construction Battalion". Depending upon context, "Seabee" can refer to all enlisted personnel in the USN's occupational field 13 (OF-13), all personnel in the Naval Construction Force (NCF), or Construction Battalion. Seabees serve both in and outside the NCF. During World War II they were plank-holders of both the Naval Combat Demolition Units and the Underwater Demolition Teams (UDTs). The men in the NCF considered these units to be "Seabee". In addition, Seabees served as elements of Cubs, Lions, Acorns and the United States Marine Corps. They also provided the manpower for the top secret CWS Flame Tank Group. Today the Seabees have many special task assignments starting with Camp David and the Naval Support Unit at the Department of State. Seabees serve under both Commanders of the Naval Surface Forces Atlantic/Pacific fleets as well as on many base Public Works and USN diving commands.

Naval Construction Battalions were conceived of as replacements for civilian construction companies in combat zones after the attack on Pearl Harbor. At the time civilian contractors had roughly 70,000 men working U.S.N. contracts overseas. International law made it illegal for civilian workers to resist an attack. Doing so would classify them as guerrillas and could lead to summary execution. The formation of the Seabees amidst the aftermath of the Battle of Wake Island inspired the backstory for the World War II movie The Fighting Seabees.

Adm. Moreell's concept model CB was a USMC trained military equivalent of those civilian companies: able to work anywhere, under any conditions or circumstances. They have a storied legacy of creative field ingenuity, stretching from Normandy and Okinawa to Iraq and Afghanistan. Adm. Ernest King wrote to the Seabees on their second anniversary, "Your ingenuity and fortitude have become a legend in the naval service." They were unique at conception and remain unchanged from Adm. Moreell's model today. In the October 1944 issue of Flying, the Seabees are described as "a phenomenon of WWII".
