My observations:

1) Heavy Duty
2)Portal hubs
3)NDMS rubber tires driving the tracks

I expect it is from a UNIMOG or a tractor or something along those lines.

I don't think the entire assembly was taken off a tracked vehicle due to the presence of the NDMS Tires. Also the tires are paired so I expect it to be from a UNIMOG type of vehicle that a tractor.

What vehicle do you think it was sourced from?

I second that.
It was indeed a retrofit job.
This is what I found out about the tracked jeep in question.

"The KAM Sno-Ball was developed by KAM Industries, Boise, Idaho in the 1940's.
The first model was produced in 1957. This machine consisted of a double-belt track assembly with dual drive wheels and dual idlers driven by a Cle-Trac planetary differential, connected to the vehicle steering wheel. Any conventional automobile could be converted to an oversnow vehicle by removing the running gear and differential, mounting the chassis over the tracks, fastening the springs to the track assembly axles, and connecting the drive line to the planetary differential. Various models of Jeeps and Chevrolet pickups were converted to oversnow vehicles in this manner. The last models of the Sno-Ball machine were not converted automobiles but were constructed as complete units with aluminium custom cabs and aluminium framing. These vehicles were used extensively in Idaho in the snow survey activity for over eight years."
