“Mobile Mattress” Radar

From Japanese Electronics, OPNAV-16-VP101, Photographic Intelligence Report 1, Air Intelligence Group, Division of Naval Intelligence, Office of the Chief of Naval Operations, Navy Department, January 1945:

“Mobile Mattress” Radar

A later, and apparently more efficient, Radar type is the “Mobile Mattress” or “Mark I, Model 2”. The Radar operates at 200 mcs. and is identified by a small screen (14′ x 7′) mounted on a Japanese standard army trailer (type 94).

This Radar is being used more and more for land-based search, either alone or in conjunction with older types. It is frequently seen mounted in emplacements, suggestive of a permanent siting.

Below are reconstructed drawings made from photos of the Kwajalein set.

The shack, antennae, revolving mount and trailer may be separated for shipping purposes.

Japanese Mobile Mattress Radar and Trailer

Namur, Kwajalein, Marshall Islands

LOCATION    KWAJALEIN
TYPE   (MK. I, MODEL 2)   “MOBILE MATTRESS”
ANTENNA    14′ x 7′ x 1 2/3′
FREQUENCY    200 MCS
P.R.F.   800 – 1500 PULSE   3 1/2- 12
MAXIMUM RANGE    100 N. MI.

The Mobile Mattress captured at Namur, Kwajalein, was mounted atop the standard concrete power house. Although the set is badly damaged, it is still possible to establish the important recognition features.

Note the similarity in design between this and the Attu type screen. The Mobile screen is much smaller, however.

Several additional views of the “Mobile Mattress” or Mark I, Model 2 are shown for familiarization. This set is very probably the best Japanese Search Radar in general use at present. The frequency is 200 megacycles per second and the maximum range is 100 nautical miles.

Pilot Flew Goering to Captivity

Associated Press has published an interview with Mayhew “Bo” Foster, the U.S. pilot who flew Nazi leader Hermann Goering to the 7th Army’s headquarters for interrogation in a Piper artillery spotter plane: Pilot Recalls Nazi Leader’s Capture.

It was May 9, 1945, the day after World War II ended in Europe. Goering, Foster and officers from the Army’s 36th Infantry Division gathered on an airstrip outside Kitzbuhel, Austria, to transport the war prisoner back to Germany in a two-man reconnaissance plane….

Goering, 52, had surrendered to the U.S. Army’s 36th Infantry Division the day before, and was now being delivered to Foster for transport….

The main problem, Foster said, was getting the two of them off the ground. Goering weighed 300-plus pounds, and the nimble, lightweight Piper L4 that Foster piloted in his artillery spotting missions wouldn’t support both him and Goering.

They’d have to upgrade to an L5, a slightly larger aircraft Foster hadn’t flown in years….

There was just a single jeep at the airstrip to meet the arriving flight. Foster rode with Goering to the gates of the 7th Army Headquarters and formally turned him over to the intelligence officer without ceremony.

7.63-mm Mauser Pistol M1932

The following report on the German Mauser C96 “Broomhandle” automatic pistol was published in Foreign Military Weapons and Equipment, Vol. III, Infantry Weapons, Pamphlet No. 30-7-4, Department of the Army, 1954.

7.63-mm Mauser Pistol M1932
(7.63-mm MAUSER SCHNELLFEUER PISTOLE MODEL 1932)

Broomhandle Mauser C96 Pistol

This Mauser pistol was first manufactured in 1896. An intermediate between a pistol and a machine carbine, it was the first successful military automatic pistol developed and, except for minor modifications in 1912 and 1932, has retained its original features.

Originally designed and produced for police use, it was widely used as an unofficial substitute arm by the German military forces during World War I. After World War I, it was largely replaced by the Luger M’08 and the later Walther designs. It was widely used in Russia during the 1917 Revolution and is still found in substantial numbers throughout the Orient and Central Europe. The weapon has been manufactured by Spain, China, and Switzerland. It is unique in design in that: (1) All parts are fitted together or dovetailed and only one screw (in the pistol grip) is used; (2) it has a slotted attachment on the pistol grip, which can be used to attach a wooden stock; (3) it has a folding-leaf rear sight graduated from 100 to 1,000 meters. The magazine is solidly attached to the receiver, and the weapon is loaded from the top by means of metal clips in the same manner as a bolt-action rifle.
