Used with AN/SRM-3 and AN/SRM-4 - in case you have a DASH helicopter control system that needs testing....

The Test Set Target Control System AN/SRM-4 provides the facilities to test the over-all
performance of the Target Control System AN/SRW-4B(DASH). The AN/SRM-4 test set is capable
of receiving, decoding and displaying rotary wing drone aircraft commands transmitted by the
AN/SRW-4B(DASH) system. By analyzing the test set front panel indications resulting from
monitoring AN/SRW-4B(DASH)·system transmitted signals, system maintenance personnel will be
able to isolate system malfunctions to one or more system components and/or component parts
is possible when the AN/SRM-4 test set is used in conjunction with the signal generating
capabilities of the Target Control System Test Set AN/SRM-6.

Can anyone tell me what this crystal and oven case was used with?
Contract number is NOw(A)63-0311, possibly a 1963 contract?
It was made by Esterline Electronics Corp (cage code 82505).
It has a place for 6 dual crystal ovens and 39 crystals marked chan 1 through 39.
The case is grey indicating probable navy,
The SRM implied Shipboard Radio Maintenance, but, what equipment?
The crystal ovens are round and plug into an octal socket, kinda standard.

 Any ideas??
