Yes Dunc and I had a visit about it and we thought that it may have been the second style R G built. It doesn't have the Timken bearings in all the spots the later ones did. The cable drums are a little smaller and built lighter than the model T or the R or even the model N. It is mounted on an Aliss Chalmers model LO and is made for that application. The LeTourneau Ident plate shows serial number B 5-- L ?

I'll ask the guy here that may have something. Be worth sending a note to Letourneu university, they'll have the info for sure. http://www.letu.edu/_Other-Resources...u/history.htmlhttps://museum.letu.edu/collections

As unusual as that cable power is, The LO is even more so. Not many survived with the engine in it's original form. You wouldn't have a picture of that tractor would you? I have 2 model L tractors and they are both hydraulic equipped. One has the pump on the front of the motor, the other has the pump down on the side of the trans case running off the counter shaft.

This one is only equipped with the cable control, the engine is original.

IIRC, the LO came with the Hesselman engine (oil-injected, sparkplug ignition, gas-engine level compression engine popular in Europe for awhile)...
Had a batch of little manuals on Wauki-Hesselman models, descibing the special high-tension mags and plugs; think they're all gone, but will check if anyone wants one...

I would sure like to have one if available. P M me what you need for one and I'll send it to you. This engine would be an Allis-Chalmers Hesselman , the linage goes back to the Stearns engines. But I suspect Hesselman specified the fuel and ignition system. So I'm sure it would be helpful.

The gas engine is almost the same except the heads and the injection pump as I recall. Most operators gave up on the Hessleman set up and converted them to simple gas operation. Pistons and sleeves and valve train are also the same as the Allis A or late E tractor. For some reason the gas tractor used 2 carbs on the single / common intake, one right and one left hand linkage. Bud, if you find a couple of those I'd be interested as well. I think the Monarch 75? was the predessor to this model. They used the big Leroi 4 cyl RAI in that version

Been downsizing for a couple years (off and on) so not sure what's left or where it/they might be; will check the logical places in the next day or two and advise.
