Aftermarket Nexus track chains

Hey everyone, there is a used farm equipment dealer near me that has a new set of Nexus NXS5C272 track chains and he cant figure out what they are for and neither can I. They are a little bigger than something for a D2, I didn't have a caliper with me so I took some rough measurements with a tape measure and I told him I would talk to you guys and see if anybody here knows what they are. He said his dad brought them home from a auction with no information. Pictures to follow, thanks in advance for any help, hopefully we can figure out what they are so they can get a home.

Almost all the equipment dealers sell that brand, have
your buddy call one up with that part number and link count they will know what they fit.
