We have a John Deere single blade horse drawn plow from the 1920's. It has a number of 317 stamped on it. I would like to find an estimated value if possible. An offer of 0. was made for it and we do not want to sell it for less than its value.

That sounds like a pretty good offer. I would have never guessed that high and I spent part of my youth with JD A and H tractors. Your could try searching sites like these for comparables – http://www.agriseek.com/buy-sell/e/Equipment/Antique/
