Important Contents Clarification
The binder currently contains documentation specifically related to the R-390A/URR radio receiver.
There are handwritten notes from the original owner referencing other equipment (possibly including the AN/UPM-137 test set), which suggests additional documents may have been stored in this binder at one time. However, those materials are no longer present.
