Yeah, that's the venerable Revell USS Missouri kit.  It was released all the way back in 1953, and generations of modelers have built it.  The odd scale came about because at the time, those kits were scaled to fit in standard-sized boxes for distribution.  And those box sizes had more to do with how many kits fit into a shipping box, and display shelf dimensions, than with a standard scale.  Standard scales became more common, as the 8-year-old boys who built the Missouri in 1953 grew up and as modelers, demanded more refined detail than they did as kids

By the way, the kit's flat bottom has nothing to do with dragging the model across a carpeted floor.  When Revell developed the kit, the Iowas were still commissioned, active-duty vessels, and details about the ships under the water weren't readily available.

Still, as you've shown here, it builds into a nice model of the Missouri. I built it when I was a lad, though as the New Jersey.  One Missouri boxing included a little replica of the plaque commemorating the surrender ceremony, too.

I recommend the other classic Revell ships, like the North Carolina/Washington, and the Yorktowns, in any boxing.  They're fun builds, even if the kits are simpler than today's kits.

Best regards,
