If you have ever seen the lamps IHC put out back in the '70s, there are 2 of them on ebay now. Just search for Titan tractor and both should come up. These are the desk lamps with the plastic shade that has a picture of a McCormick 10-20, Regular, and a Titan 10-20. It took us 20 years but we finally got all the tracotors on the lamp. John Hall
