UPDATE: There was some interest in the Capstan winch from David’ part’s jeep that I featured the other day. Here’s some additional views of it.
You can still find parts for Capstan winches here, though they are out of the Capstan kits (which cost $2,650). Brian also runs a ‘Capstan’s for sale’ page, but appears all sold out at the moment. And here’s a little nautical history of the Capstan winch from wikipedia. And here’s some info from the CJ-3B page on the Ramsey Capstan Winch, including some pics of the brochure.
