Blower, chopper and rotator (the RCM-1), the solenoids (RCM...-3?) and the grey box was most likely communications to the siren. Thunderbolts in the 70s were (last I checked) usually set off by phone line but sometimes by radio? (Mine was set off by phone line when it was serving waldport... its a 60s bolt but it spent the first few years serving Spokane.)
Own and love a Thunderbolt 1000 and a Model 5.
I have many hobbies and interests. And I love them all.
