Great high 5 mascot! Don't know how you always come up with a picture for the purpose.

And moreover it was safe.
Yes. In addition to the reasons you gave, if 2 switches were pushed for different directions and both contactors provided voltage & heavy current at same time to pump, things could have gotten very interesting. This way only the solenoid coils would get power at once and at worst, a fuse would blow.
Would sure like to see a picture of the window mechanism if you have one in your spare parts pile. With a bidirectional pump, did it have the big spring like the Packard?
