Dave, Does it look anything like the "Unidentified Crawling Object" story in the Artical Archives?. I tried to send you some pix, but you left a non-working e-mail address.

Similar in general Steve but the details are different. The front track wheels on mine are two stamped plates bolted together over a hub which carries the bearings. I cannot tell from the picture but my drive cogs are also stamped plates with access holes punched through the main web and build-out cog plates welded inside and out to build up the engagement area. Independent fenders guard the operator from the tracks. The seat on mine has been changed but I beleive it was originally a cast iron or sheet-metal pan on a large strap type spring. It has a 3+R transmission and wet steering brakes on two levers which were originally fitted with lock tabs. The transmission/differential unit is independent from the engine/clutch assy and coupled with a short jack-shaft wit two dry universal joints. Large U-bolts with "WOOD!!!" blocks couple the third members to the frame. It looks for all the world like someone took a wheel-tractor, removed the drive wheel hubs, and replaced them with planetary hubs for the track.
Yours, if I were to judge by the seats back and armrest configuration, may be related to an early catapillar. Especially if it uses a tiller steering system.
I am only guessing, however, the area I grew up in around Fresno, Ca. had more field decorations than homes. Some of which were old gas cats similar in appearance to your UCO (G2??).
Don't know what's with my e-mail (caps??) usual aol fun I'm sure, but I will check back here regularly during the work-week.
thanks, Dave

Dave, I have done a lot of reserch on my U.C.O. and it is not a Cat. It uses two steering clutch levers and foot brakes. It also has a large winch on the back. Every one that ive contacted either thought it was "this" or "that" or never seen one. During my serch, I have come accross a lot of different "brands" of small crawlers, and yours is another one that I can add to the list. Its amazing on how many different types of machines that were built and didnt survive. If you ever have a chance to get some pix scaned, I would sure like to see it. Sorry that I cant help you. But if I come across anything I will be sure to let you know. Steve T.

Ok Steve, Later in the day I found some other crawlers with similar configurations to yours that were definitely not cats either. Also got a good picture of an OC3 and mine is very close +/- a couple of details. The frame on mine is a simple U-channel and the picture I caught shows a doubled frame (one over a smaller, stiffening frame) but that could be a specific year model change. Now the real confuser has to do with the serial number. Could the HP prefix on the serial number HP5239 indicate that the original unit was a Hart-Pahr to which an Oliver engine and OC3 running gear were installed. I can see how this could happen if one had two dead tractors (or even three when you consider the oversized tread). If that is the case though the serial number traces back to 1913 for the year in which Hart-Pahr issued numbers in this range.
Ahh-well the hunt is on, thanks and good luck Steve. Likewise I'll let you know if I find anything regards yours.

Dave, The OC-3 was a crawler built by "Oliver-Cletrac", hence the model name "OC-3".Oliver Co. bought out Cletrac and added their name to the Cletrac machine. Then White bought Oliver, and someone else bought Oliver. Not sure, but I think that they are all now a part of Tenneco Corp. You didnt say what engine that was in yours. Most probable that its a Continental or a Waukesha. These two makers were the most popular. I dont think that Hart-Parr ever got into the crawler business, Just tractors. My crawler uses VERY thick 3in. channel iron for the engine and track springs support. It also uses 4in. channel iron to house the front idlers, track rollers, and track adjusting spring. Please let me know if you ever find anything out on your machine. And Im going to have to slap the next guy that says that mine was a "mail order kit" from Sears,,, HA!

Steve, it could be I am getting warmer. I just saw a photo of a 1947 HG42 that could be a twin to mine w/o the blade. How do you distinguish between the various engines?? Mine has three small freeze plugs on the left and an accessory mount with a fourth (larger) freeze plug in it, could be for a jacket heater. F-M 4cyl magneto, the governor is mounted to a timing gear cover extension on the right (facing rear). The starter
is on the left. Lifter gallery cover and the intake/exhaust manifolds are on the right. Is this enough to guess with??

Dave, It is starting to look like this company used some one elses engine in their machine. is there a name on the engine?? possibly a Waukesha,Wisconson,or Continental, or other various mfgs. It doesnt look like it was built by any of the "large" Mfgs. If you ever get any pics scanned of it, please send me some. Steve
