I remember seeing that photo many years ago, but since then believe the information in the caption is suspect. Even though the badge on tractor in the photo looks to say 600 or 800, all the information I have come across indicates that the first tug after the 2N BNO was the model 621-62 built in 1962 and ordered through the U.S. Army Corps of Engineers. Logic tells me the tractor would not be a 660 since the tug would have no use for a 3-point hitch/hydraulics or a PTO just to pull around aircraft or carts. Every one I've seen so far also have a 4-speed transmission, even into the 1970's, and the 621-62 used a torque convertor instead of a traditional clutch (hence the oil cooler in the photo). Since the 600 and 601 look identical from distance, they would be hard to distinguish from that photo.
The reason I have taken an interest in tugs is that I own a model 621-62. I am positive it was used on a military base as there is one within 100 miles of where I purchased the tractor and there are labels in the tractor indicating use by the USAF on an airstrip. The brass tag says it was a wheeled tractor used for 'IND. GED (Ground Equipment Depot) TOWING". I suspect it didn't tow many planes but was used to move around ground support equipment for planes. It was originally equipped with pintle hitch from what I discovered.
The N-News Spring issue actually has an article on a restored 621-62.
