What did these DC motors originally use,an older rectifier,motor/generator set or did they use DC city mains?
-
They are DC. And I've been around much quieter DC motors.

@bw4t The majority of the organ is on 6" with the following exceptions: Great 10", Solo 15", 16' Opheclide 20", 32' 16' 8' Bombarde & 8' Orchestral Trombone & 8' Tumpet Harmonique are on 25"

This is fantastic! The Newberry is one of my favorite organs. Heard it many times when I lived in New Haven. Thank you for sharing this clip!

There are two sets of switches, one set is at the console and the other set is next to the blowers.
There is a computer controller, but it's a separate system. It is only used to run one of the blowers at a very slow speed, the purpose being to circulate humidified air through the entire wind system of the organ during the heating season. They are also both Spencer blowers =)

My church can start up their four Spencer blowers with one press of a button, fully automated. Nice to see some manual labour though, orginal breakers and all :-). What manufacturer of blower are these?
I see two blowers, right? And you started just one? Interesting how long it took before it really wound up and filled the reservoir. Three phase current?

The second one is there for redundancy. Most people turn on Blower 1, and we have the humidification system running through Blower 2 since it gets used less. When the humidification system is running through the dry winter months, it runs the blower at a very slow speed to circulate the air from the humidifiers behind the blower room. It's a 4 stage start up, and yeah it does take some time before they're going full speed.

This one is a "static reservoir" which regulates the static pressure from the blowers. From here, the main windlines feed the rest of the organ. Since this is a very large organ (it has over 10,000 pipes), there are many smaller reservoirs, much like this one, placed throughout the organ. Even a small pipe organ will usually have at least one reservoir. Their basic function is to provide a steady amount of wind at a specific pressure.
