WWII Advertorials


Na laatst in een gesprek over de M4 Bajonet, vertelde ik dat de M4 Bajonet een na-WW2-oorlogs produkt was. Deze werd tijdens de Koreaanse oorlog gebruikt en geproduceerd. Ik moet helaas concluderen dat ik hierin fout zat. Hier het resultaat van mijn onderzoek.


How the M4 came into excistence


In October 1943, Headquarters, Army Service Forces directed that a project be initiated to develop a bayonet for use with the standard carbine. It was further directed that several types of bayonets or adapters to permit the adaptation of the trench knife as a bayonet for the carbine be developed and procured as early as practicable. This project was initiated in the latter part of October 1943.

Three types of carbine bayonets were developed, the Carbine Bayonet T4 had a clamp to fit over the front sight and had a round cross-section blade 7 inches long and 3/8 inch in diameter at the hilt, the Carbine Bayonet T5 had a clamp to fit over the front sight and the blade, which had a diamond shaped cross-section, was 7 inches long and 1/4 inch by 3/8 inch at the hilt, last was the T6 Carbine Bayonet with clamp to fit over the front sight and a knife blade 7 inches long and 3/4 inch wide, having the same contour as the blade of the M3 Trench Knife.

In order to comply with that portion of the directive from Headquarters, Army Service Forces, wherein an adaptation of the trench knife for use as a bayonet was to be developed, the following described modified trench knives were developed through the coordinated efforts of the Ordnance Department and the Imperial Knife Company personnel.

The T8 Knife consisted of the modification of the front guard and butt plate of the M3 Trench Knife. The butt plate was so constructed as to have incorporated therein a single catch. Before it could accommodate the T8 Knife the carbine barrel required the addition of a bayonet stud to be pinned to the barrel.  Upon inspection of the T8 Knife it was found that if the bayonet catch was accidentally depressed, the bayonet would come off the carbine. This was remedied in the next model.

The Knife, T8E1, differed from the T8 in that a second bayonet catch was inserted into the butt plate of the knife. This knife, together with the new carbine front band bayonet lug assembly described in a previous chapter, permitted ready assembly and removal of the knife to the carbine.

In January 1944 samples of the T4, T5, T6, and T8 Carbine Bayonets were sent to the Infantry Board for inspection and test. Based upon the report of test of these items (Infantry Board Report No. 1586), Headquarters, Army Ground Forces requested that the following be accomplished:

a. The M3 Trench Knife be designated as Limited Standard and its manufacture cease with the least practicable delay.

b. The T8 Carbine Bayonet be standardized and manufactured in lieu of the Trench Knife M3, inasmuchas the modification in no way detracts from its use as a knife, but instead enhances its value by making it a dual purpose weapon.

c. The catch on the T8 Knife to be the same as that of the T8E1 which was merely demonstrated to Head­quarters, Army Ground Forces personnel. (The model T8E1 incorporated a double catch which corrected the faults found with the catch of the T8, as tested by the Infantry Board.)

d. The new front band bayonet lug assembly be adapted to all carbines issued to Army Ground Force Units.

e. The Carbine Bayonet T8E1 be issued under the same basis of issue as prescribed for the M3 Trench Knife, with a priority of issue to those troops armed with the carbine. The Knife T8E1 was standardized in May 1944, and designated as Bayonet-Knife M4. It is to be pointed out that the Scabbard, Trench Knife, M8A1 is usable with the M4 Bayonet-Knife.
