LeRoi Model S

[jawgroth]

Started tearing down this 2 cylinder radiator cooled model S. Does anyone know what the attached symbol is on the block. It looks like and large S with an 'F' in one section and 'Co,' in another.
Also does anyone know waht the number after the model number means on LeRoi's. I've seen RH2 and RH3. I'm guessing either PTO option or rotation direction or ???

I currently have 2 single cylinder hopper, one 2 cylinder Radiator, 1 four cylinder D91, a D176, a d226, and a Tractair125. 3 run, other are parts engines.

The S is just a casting mark as most le rois have it somewhere. Is it a hopper cooled or rad and what is the bore. If rad look on the side where water enters the side and look for casting numbers that is the cast date. Im guessing it is a model M or varient.Also what extra parts do you have. Ed the le roi man

It is a radiator cooled Model S. 3 1/8" bore X 4" stroke. The casting date is 7 15 26. I got the valves out tonight. Next are the pistons - both are cracked but luckily they where all the way down in the cylinder. I will turn down a piece of oak to 3 1/8 and drive them out.
