Jerry, I pulled out my 48 page original brochure for 1951 Chevrolet Trucks. The 235 splash oiler was called "Loadmaster 105" and, you guessed it, the engine had 105 horsepower. There is only one picture of the chassis where you can sort of see the valve cover decal... see attached picture. It would actually be 4 decals separated by the 3 sets of vertical bars on the splash oiler valve cover. 1. Load- 2. Master 3. 105 4. Engine
The font looks to be the same as the more common "Thriftmaster" decal. Kent
