Blue Ridge Models also announced today the release of their 1:350 USS Albacore, AGSS-569 in what looks like, from box art, the boat's 1960 conversion that added X-configuration control surfaces and hull-mounted dive breaks. Also hinted at in the box art is the contra-rotating propellers that were incorporated in 1962.
Here's the link to the the box art: http://www.shipmodels.info/mws_forum/viewtopic.php?f=2&t=109821
Now a museum ship in Portsmouth, NH, the boat's technical achievements and reconfigurations are detailed here: http://www.ussalbacore.org/html/albacore_story.html
And for sub modelers looking for some color on their display shelf, with appropriate backdating, you can model the Albacore as of 3-specific days in the summer of 1959: http://www.ussalbacore.org/html/flotsam_jetsam/fj_orange_submarine.html
