Keith,
The style of beacon light shown in the photo, rotated. Later, solid state beacon lights had four fixed bulbs and reflectors, spaced 90 degrees apart, that flashed in sequence. Those didn’t come into common use until after the BN merger. They were larger in diameter and considered to require less maintenance because they didn’t have any moving parts.

Did the beacon rotate in a 360 degree circle or did it go on and off? Thanks again.

It's possible that one or more Nebraska-based SW1s got them, but I haven't checked photos to make a more definite determination. Hol
