If I remember correctly the Oliver plows were painted red with natural handles. At age 56 I was a little late for these types of plows. My Granddad sold Oliver products and in the Middle section of TN several tobacco farmers used horse drawn equipment until the late 50's. I have several price lists from the 30's-40's. A 1938 Oliver plow price list has 22 plow models. The list price for the model 19 was $15.50 and replacement parts such as handles cost $1.90, chilled shares $1.70 and main clevis .40.
These prices were effective August 10,1938.
