I have check Google, Ramsey Products, & searched for PTO's both long and short version.

Here's what I have a Rockwell T221 Transfer case with what appears to be a Ramsey PTO mounted on the side.
Also has a speed o cable attached to the transfer case.

1. What is it exactly? Is it really a PTO?
2. How does it work?
