Helldiver, I think you are the senior Navy vet here at the Outhouse so there's probably nobody else out here who's shared your experiences. 
When my Mom moved into her apartment her neighbor was a WWII Navy vet who spent the entire war in the South Pacific. He said they were served a lot of mutton (lamb) from Australia and New Zealand, and they had it more often than the modern USN serves variations of roast beef. He grew to hate the smell of mutton cooking and never ate lamb chops again. As for your definition of "horse cock", it sounds like the generic sandwich meat we used to get aboard ship. Not bologna, not salami, no taste, just... some kind of meat. Don't believe they ever served us horsemeat in my era of service, but it may have been preferable to the "mystery meat" portions that were served as chicken fried steak aboard USS Coral Sea on my first two cruises.
