Type 93 flamethrower
The type 93 flamethrower was developed by the Japanese for uses during World War 2. It was largely based on the American design used during World War 1, but used a different blend of fuel based on the flammable materials available to them.
The Type 93 flamethrower consists of a gun connected to a fuel unit by a hose. The fuel unit consists of three cylinders: two outer fuel cylinders and a central cylinder. Each is about a foot long, and 6 inches in diameter. The cylinders can contain up to 23 liters of a mixture of gasoline, rice wine (sake), and tar. Pressure is controlled by two manually-operated needle valves. This tank assembly was fitted with straps to permit it to be carried on the operator's back like an infantry pack.
The 45 inch fuel hose was made of reinforced rubber tubing, with brass fittings on both ends. The flame gun, three to four feet long, was a 1-inch diameter tube with a fuel ejection handle located near the hose connection, and a 1/4-inch nozzle with the firing mechanism attached to the other end.
