Mystery Capstan Help

[sailor1924]

I have an uninstalled electric capstan with a chain gypsy that was furnished by the PO when I bought the boat. Unfortunately he's passed away so I can not ask him questions.
I've been unable to find information online and identify the manufacturer so I'm turning to the community for help. I'm posting some photos and hope that someone will recognize the unit and be able to point me in the right direction.
I'm reluctant to go through the installation process unless I'm pretty confident that the equipment will work for the boat and ground tackle I'm planning.
As you can see there a 700 stamped into the chain stripper. There is also an 8 marked on the gypsy though it probably can't be seen in the photos. The transmission angle drive is by Bonfiglio a VF49. There are no markings on the motor. The gypsy locks with a small toggle.
I'm sure that this capstan on one very similar was previously installed on the boat as there are remnants of installation in evidence.
I wonder if the 8 on the gypsy refers to 8mm chain. There is very little chain being used in the rodes that came with the boat. I'd like to add a couple of hundred feet of chain but need a working windlass to do so.
The boat is a Pearson Countess 44 and weighs about 28 or 29,000 pounds.
I'd like to be using a 60 pound Mantus with a chain rode but without a windlass I don't think my age and back will permit it.
Thanks for looking.
