On the Ball Pilot Tow Bar 1970's
 

Any idea what a vintage On the Ball Pilot Tow Bar from the 1970's would be worth. Asking for a friend. And best place to sell it. thanks

The vintage NMW tow bars sell for about $300 to 400. I am not familiar with the On the Pilot Tow Bar.

Here is a photo

I'll take a wild guess that these aren't worth much since you have to attach it directly to your bumper and scratch the hell out of your car. No self respecting gear-head in the late 60's early 70's would have wanted to use one, hence decreasing the value.
