Thanks! I looked at a few pictures of MD-3s and I think you're correct. In many of these cases I only have the description of the person who posted the picture to go on because I don't know them well enough to ID it myself.
The Wings of Freedom Aviation Museum has a yellow Clark tug that appears to be marked as "WLG194":

While looking for pictures of the above tug for this post, I found out that they picked up a heavy-duty tug in February 2019. Coincidentally, it appears to be a TA-75! This one is painted white and marked as "008566". Note that it has the same light blue, single digit number as the first tug:

Finally, they apparently also have a Willys MB "Follow Me" aircraft guide jeep on display – although it is not clear if it originally served in this role or has simply been repainted as one. It is marked as "4640885":

Now we head south-o-the-border to check out two Argentinian aviation museums.
First, the Museo de la Aviación Naval Argentina (Argentine Naval Aviation Museum) has two aircraft tugs.
One is a S32A-31 that was used aboard the aircraft carrier ARA Veinticinco de Mayo. In another coincidence, based on appearance, I believe this is the same model of tug as an MD-3:

Two is a Douglas DT Taskmaster, number 4, also used aboard the ARA Veinticinco de Mayo:

Second, is the Museo Nacional de Aeronáutica de Argentina (National Aeronautics Museum of Argentina).
While it may not be GSE strictly speaking, the museum has a IAME Pampa that was designed and built by the Industrias Aeronáuticas y Mecánicas del Estado (State Aeronautical and Mechanical Industries). It also certainly could have been used to move aircraft:

It is also worth mentioning that the museum has a
Tucker Sno-Cat and at least
two other tracked vehicles that were used in Antarctica by the Argentine Air Force.
