4 Roller OC-3

Found this listed as a 1953 OC-3 on Craigslist. Interesting features are the 4 rollers and the name plaque on the track frame " Chicago Pneumatic"  Also I'm wondering if the grill is a factory guard? It appears to be the same stamping as the early Cletrac pattern. Looks too well made to be a home fabrication. The under carriage looks to be in great shape from this picture. Ad says it's been on the family farm for last 25 years.

That track frame was off of a Chicago Pneu. rock drill.  A lot of the drills used Oliver undercarriage parts. I think somone just made that grill guard out of a piece of a Cletrac grill. If you saw it close up, I don't think it would look as good as you think it does.

Strange, I just found another one of those Cletrac pattern grills on what looks to be an HG on Craiglist. Could it be coincidence that both of these were home fabricated?
