Here are some photos I took of the Clarktor-6 towing tractor examples on display and in action at various events and museums. One example in Tillamook was displayed as a Blimp Tug so I have included it separately.
More recently, The Clark Equipment Co. produces Clark Airfield Tugs
I have placed other unidentified aircraft tugs on the Unidentified Aircraft Tugs page.
