It sounds like a BG or BGH (the H meaning "hillside", which is a slightly wider tractor.) Since it says Oliver, there's a good chance that it's a BGS or BGHS. S meaning Studebaker as the engines are Hercules JX series made during the War for Studebaker trucks. After the War, unused engines were sold to Cletrac and installed in the B tractors. Supposedly they are better balanced for higher speed in the trucks.
