What is this atop the stearing column

[Vortech]

Is this the reverse switch for a truck with 3 on the tree?

Judging by the orientation to the linkage that would be my guess, but it appears to be “owner engineered”. According to the 1960 Accessory Installation Manual the factory offering was operated by a switch attached to the steering column under the dashboard:

We've used the 48-54 Chevy brakelight switch to "owner engineer"(I love that term!)backup lights on many 3-on-the-tree vehicles over the years--did one just a couple of months back. Link to pics below, compliments of Rock A/P

Luvbowties, is this used under the dash or in the engine compartment? Is there a write up on this?

No write-up on it, sorry. I always found a way to mount it under the hood near the linkage just to where reverse would catch it to activate the back-ups. They are easy to mount and adjust(bend)so as to contact where you wish it. Never had one to go bad, either, even after several years' use.

IIRC, the 1st one I installed was on a '54 Chevy ,for a customer where my dad ran a full-service gas station, & I had begun doing minor garage repairs. (I was 13 at the time, but hungry?!?) That's the one I saw function from about '56-'69, and one I had taken off a '48 Chev that I was parting out.
