[Boatanchors] Bliley Standard Frequency Crystal Unit Type SOC100

[Gerry Steffens]

While cleaning out, I found what appears to be the Instruction sheet for the
subject unit.

The sheet may be from 1936, although the manual it was in appears to be
1942.

It includes sections titled: Characteristics, Operation, Mounting, Guarantee
and a schematic.

It was found in an original manual for BC-779A and RA-S4-A.  This manual
says manufactured by Hammarlund but has a stamp that says manufactured for
Hammarlund by Howard Radio Co.

Is this worth saving?  It looks like the unit might be a crystal calibrator
for a BC-779A  Super-Pro.
