you might want to investigate those links Tim, there's only two I found that actually have lino, Forbo and Armstrong, the rest deal vinyl ... and Armstrongs' appear to all be
mottled colors, 2.5 mil, and they seem to sell more tiles than roll goods .... comes down to Farbo being the originating supplier of the battleship grade thickness

I also found a number of art lino suppliers with "battleship" lino, all gray, and a marine forum where it was claimed battleship lino was so named from the battleship gray color, not from being used on ships, which may explain all the art battleship lino being gray
