Hello
Google up the Lightship Modelers gallery page, or Digital Navy Ambrose Lightship page or Chesapeake Lightship page. I couldn't find a walk around of the NANTUCKET(WLV-117) which is the ship you are building. The radial davits didn't change that much over the years, as a crewman on the NANTUCKET II(WLV-613), I recall we had the same "crank 'em out davits as all the prewar cutters had like DUANE and BIBB. They were a pain in the *&^ to launch a small boat, took almost the entire deck force to lower a small boat. Also if you have access to the old PYRO plastic NANTUCKET, I believe they are the same type of davit.
