I think I have shots of one of those in operation from the Ederville show in Carthage North Carolina a few years ago. That show occurs every fall. That is the ACMOC show, so lots of Cats from the earliest to the latest.
There is another show over the 4th of July weekend each year in Denton NC. That is a larger show and not Cat specific. Many things from the earliest Case steam power right up to the latest from current makers. But, we did have a Crawler specific year and so maybe one of these was there.
Me, I have a fondness for the early Deere crawlers having both a 1958 420 and a 1978 350. Small machines, to be sure. If I ever do add a Cat, it would be a little old D2.
