This relates to my interest in survival items. It turns out that a lot of pioneering took place in relation to One-Man Pneumatic Life Rafts (Ref 1). When I went looking for some of the items shown in the book I found them. Rather than put them on various web pages I'm making a new web page so they can be toghther.
Note that pilot's sat on a "pack" that contained the life raft and survival kit. They both changed over time but the size of the pack remained constant. 15" across front, 14" deep and 2" thick. That limits the size of what can be stored.
The MX-138 is a larger RADAR corner reflector probably used on larger life rafts or life boats. The MX-137 is a smaller version that will fit a W.W.II pilot's seat pack.
Prior to the MX-137 one man life rafts used the CPT-2 Radar Beacon. It could be picked up by the SCR-521, SCR-729, AN/APN-12, Navy ASE, or British MK-11 Search Radar units.
The AN/CRC-7 VHF Search and Rescue Transmitter-Receiver was the next development. 140.58 MHz Tx and Rx. Tech Order AN 16-30 CRC-7-2.Photos

I expected this to be about 15" long but it's more like 28.5" collapsed and 66" extended. Let me know why a part for the C-2 life raft would be this long.

This is 14-3/4" long so is under the 15" limit for a seat pack.
With any light at sea it's desirable to illuminate as much of the sky as possible. A light coming from a lamp worn on a person will have half of it's light blocked. By floating this light some distance from the life raft and the man on board more of the sky is illuminated.
When not is use, turn off. Life of battery approx. 24 hrs., with Mazda 131 (1.3V., 0.10 Amp).
Check battery periodically.
To use as flashlight, interchange Mazda #131 with Mazda #112 (1.1V., .22A., TL-3 bulb.
Life of battery is reduced with #112 Lamp.
Fig 3 Maintenance - Lens unscrews from body.
Remove base cap to replace battery.
Be sure lens and battery cap are screwed tight.
Fig 1 Operation - Turn cap at base to left until battery housing is free.
Extend grip battery housing and turn to left until threads are tight,
Attach end of cord to life raft.

Patent Appl'd for (see 2366929 below)
Fig 5 No. 112, No. 131 & "2-Cell" LED, all E10 base
The "2-Cell" LED turns on at 0.48V so does work with one cell, just not as bright as with 2-cells. This is a Joule Thief circuit.
So far I have not found a nomenclature for this item.
