The unit is a power unit for an aircraft radio set. 24 volt input and 600 volt high tension output. A similar unit is illustrated on P.314 of Handbook of Japanese Military Forces, 15 September 1944 (War Dept TM-E30-480).
The unit comprises the generator bolted to a metal box. The whole is painted in Army brown.
The Generator is approximately 240 mm long. The brush gear is on the Left Hand Side (LHS) with the cooling fan on the Right Hand Side (RHS). The cast generator case is approx. 112 mm in diameter. Two flat feet are secured to the metal box by two bolts each side.
The RHS has the cooling fan cover in place. This has a circular flat end, approx. 90 mm in diameter, with four mesh covered openings to allow for air flow. It is secured by a knurled knob that locks down on a slot in the top of the cover. The cover is badly dented on its lower side. A similar knurled knob is present on the LHS, however the cover is missing for this side. This side has also been damaged with some of the brushes falling outside the generator case and only connected by the electrical wiring.
There is (bullet?) damage to the rear of the housing. A manufacturer’s plate (40 x 50 mm) is situated in the middle of the top of the generator housing. This is badly corroded and no manufacturer’s logo can be made out. To the right of this plate is a small plate with an arrow showing the direction of rotation.
The box under the generator is 240 x 140 x 70 mm deep. The base of the box is a metal sheet approx. 2 mm thick that extends approx. 6 mm to the rear. Two extensions of the base approx. 2 x 45 mm long are positioned approx. 50 mm from each side of the box.
To secure the box in place there are two metal pieces riveted to each side of the box. These are cast with a semicircular piece at their outer end. It appears that these fit into a slot or over vertical circular bars that hold the box and hence the whole unit in place. These semicircular pieces are 25 mm wide for 25 mm from their base with a 4 mm diameter slot. The outside then tapers for 15 mm to an approx 16 mm external diameter flat top with an 8 mm internal slot.
On the front face of the box are two threaded electrical outlet/inlet ports with a fuse box mounted between them.
The electrical ports are circular ports with a 40 mm square base that is attached to the box by four screws, one in each corner. The circular ports are approx. 33 mm in diameter and protrude approx. 20 mm from the face of the box.
The LHS port commences 23 mm from the edge of the box. Above this is a small plate 20 x 5 mm screwed into the box. That bears the numeral “2” on a black ground. The electrical connection is by means of three prongs.
The RHS port commences approx. 115 mm from the edge. It has a similar plate screwed above it that bears the numeral “3”. The electrical connection has seven smaller diameter prongs.
Between the two is the fuse box 55 x 45 x 20 mm deep. The cover is missing. Two fuses, mounted horizontally, are present. Behind the top fuse is stencilled in white “23” in a circle. To the right of this is “0.5A”. Behind the bottom fuse is stencilled in white “24” in a circle with “5A” to the right. Above the fuse box is another plate approx. 36 mm long that has Japanese characters in white on a black background.
The base of the box is Army brown painted over black that was painted over the natural metal. The whole is showing signs of corrosion.
This unit was of the type used to power radio transmitter recievers in aircraft, including the Oscar fighter. Provenance unknown.
The unit is a varnished rectangular wooden box 100 mm wide and 105 mm tall. The front face is made up from three pieces of wood. In the left centre of the middle of the box are two circular metal lin
