The SRR-13A is a dual conversion superhet that covers 2.0 to 32 MHz. It uses 29 tubes that are soldered into removable modules, not plugged into sockets in the conventional manner. The radio is unusual not only for its highly modular construction, but for a an optically projected frequency readout. It weighs 69 pounds but seems heavier.....
Jerry Proc has some data related to SRR/FRR use in the Canadian Navy.
Not related (closely, anyway) to the four full racks, two ton FRR-24.
Lots of information on US Navy receivers of the 1950's and 1960's at Nick's web site.

Replacement Parts?
Some are still made by the oringal companies! For others,
make your own!
Pesky Switch Arms, hard to find parts used in mode and band switch linkages.
Lots of rack mount radios have dull, lifeless handles that are merely screwed into the front panel. Not SRR-13's! They have kinetic handles with handle gears. What the heck are handle gears? Why, the gears that gently extract the radio from the case when you rotate the front handles upward. And when those handle gears wear out, buy some original replacement parts.
