All American SAR- Radios from their beginning to 1968 are part of the collection.
More modern ones are (still) too expensive....
You may also read the article by Alan Tasker :
"U.S. Military Portable Radios"
(1976) "is the Navy's standard lifeboat radio. This is why it has 121.5
and 243, because the Navy can be anywhere in the world, and you need both
of those frequencies, especially 121.5 if you are apt to be far from anywhere.
The normal battery is a 6V lithium. However, Lithium is not allowed on
submarines. So, what to do? So they made a round sleeve that screws onto
the radio in place of the cap, and the cap screws onto the end of the
sleeve. The extra length of the battery compartment now can hold 4 each 1.5
Volt "D" cells." ( " " by Alan Tasker, WA1NYR)
