Need to look at the spelling or just tell me where Berger is. At the end of world war 2 my dad sold a cross motor case and a year or so later an Oil Pull. I stopped to see the man in 1971 on the way back from my brother in-law in Tulsa. He still had the oil Pull. It was close to Herman. I worked for an Oliver dealer for 16 years starting in 1960. I am in northwest Ohio. We did not sell too many 1955 tractors, we sold more of the 1950T tractors. We did very well with the 50 series tractors so most people don't trade every 2-3 years. John
