Help identifying this tow bar set-up

Looks like Roadmaster's Stowmaster, maybe an earlier version of it. AFAIK Roadmaster is the only vendor that included that angle-iron crossbar as part of the towbar. This is what gets bolted (safety-cabled) to Roadmaster's separate towing brackets.

It definitely is not a Roadmaster Stowmaster. I have one, and have been using it for over 10 years. You can see a photo of the Stowmaster here. Note the Stowmaster uses angle iron side-to-side the same as the Duncan.

I am of the belief the tow bar skipro3 posted is a predisser to the Roadmaster tow bars, as posted by j-d.
