Oil deflector on model C

I bought and tore down 7 0r 8 B's and the same for the C's plus 3 CA's. I have yet to see the oil deflector on any I tore down. All were old tractors that were not running when I bought them. They were either discarded for some reason or not all had them for what ever reason.

These are the pics of the cylinder head with the deflector. It is more clear than the drawing

I've seen them before. I have one on the shelf just like it. I saw one once on a C and several similar to it on WD and WD45 engines. My 1952 WD has one similar. I looked on AGCO Parts and it lists it for that 125 cid engine when used on a 60-H. Now what is a 60-H? Hillside All-Crop 60 combine? Also it lists a similar deflector for WD45 engine serial number 45-13087 & up. Helps with lessening oil consumption at the valve guides??? I can't remember how the one on my WD was configurated.

May be it is only for the power unit engine

Typically things like deflectors are added to prevent oil from vacating certain areas.  The thread suggests that the deflector was only used on hillside combine power units.  Could be that AC figured those power units would spend considerable time sitting at an angle (like on hillsides) and added the deflector to keep the valve train lubricated and/or the oil draining back to the sump properly.

I am finishing an engine with that deflector in it. I think I am the first one in this engine. No marks on the rods. It was in a B but it has a CR on the engine serial number. The thrust was wiped out which is the case with many power units. It will go on my 60 engine drive combine.
