Old gear driven Mandrel

[Tooly236]

Hello, I Was just curious ir anyone has seen a machine like this. The main gear is 4 inches thick x 38 inch diameter. It has a 5 hp electric motor and a big gear reduction assembly. There aré 2 different adjustable beds and the center hub is interchangeable. The pics aré bad but I just wanted to know if anyone knows anything about it and what Its capabilities would be on square tubing. Thanks

Don't see any mandrels. Looks like a bender ? with a guide shoe sitting on it ?
Here's a link that may help.
