The Japanese Type 100 machine gun is perhaps the most sought of all Japanese machine gun models of World War 2. Largely overlooked by the machine gun collecting community for decades, the Type 100 has had a tremendous upswing in interest in recent years, due in part to recognition in online gaming, and, as collecting of WWII military arms has become ever-more popular, the growing realization that Japanese machine guns, particularly the Type 100 were manufactured in much smaller numbers, and by consequence, there are far fewer specimens available than the more mainstream German machine guns. This gun was manufactured by Nagoya Arsenal and includes one original magazine and a reproduction sling. It is also noteworthy that this Type 100 has a steel buttplate. As production progressed and pressure increased to turn out more guns quickly, the Japanese instituted abbreviated manufacturing procedures. Later produced specimens of this model would have a wooden buttplate fitted instead of steel. Far less fitting time, and effort to nail on a piece of wood than to inlet a stock and fit a metal buttplate. In addition to an original magazine, a reproduction sling is also included with this gun. The Japanese were relatively late compared to other nations in discerning the usefulness of pistol caliber machine guns in close combat. This gun is the Type 100 model of 1944, and although fewer than 6000 were produced, it is by far the most produced of Japanese pistol caliber machine guns. These originally were issued only to “special” units, but eventually by 1944 were seeing more widespread issue. Visible serial numbers on this gun are all matching on the metal hardware throughout, including receiver, bolt, bolt handle, buffer, and buffer retention latch. The barrel is the original barrel to the gun. The stock is non-matching in the channel. This is common on Type 100 guns as stocks would be replaced when broken in combat. The action of this gun is smooth when operated by hand. Electronic NFA registry indicates “Unknown” in the manufacturer’s block. CONDITION: Overall appearance and finish is a combination of fine original finish, thinning in places with numerous areas of light pitting and brown patina and touched up blue in places. Bore is extremely fine, shiny and bright. Wood has been very lightly sanded and refinished retaining all the character of light bruises and handling marks from combat use. Magazine is fine, with electro-pencil markings on either side near follower denoting type of magazine as well as "SN 6148", marked on the spine of the magazine near floorplate with factory inspection and original serial number of "8525". A remarkable find! Mechanics are crisp. This is a full-auto only machine gun. Japanese Type 100 machine guns are offered for sale VERY rarely as there are not many specimens in the National Firearms Act registry, and the interest in collecting Japanese machine guns, especially with modern ammunition now being obtainable, is rising. This is a specimen for the discerning, forward thinking collector/investor. THIS IS A NATIONAL FIREARMS ACT ITEM AND REQUIRES BATF APPROVAL PRIOR TO TRANSFER. THIS ITEM IS FULLY TRANSFERABLE ON AN ATF FORM 3 OR 4 AS CURIO & RELIC ELIGIBLE.
