Some Manhattan cold war BSPs
- Steve Cichorsky scanned these and posted them to the TCI list. I figured
they might be interesting to some people here who aren't on that list.
They're BSPs issued by NY Tel. in the 1950s specific to the Manhattan area:
Action to be Taken During Working Hours in Event of a Civil Defense
Emergency, Issue B, 12/1/1956
Cordless P.B.X. Switchboards for Civil Defense Units, Issue A, 12/10/1953
