BTW, I wanted to add that it seems the name of the game, "Utah" came from one of the USS battleships, the USS Utah. (and the ship was named after the state Utah according to Wikipedia so go figure)
This is from Craig Smallish, a woodrail collector:
Craig Smallish, "Interesting fact: United Manufacturing began producing what on the surface appeared to be purely a state series, but was actually an homage to the USS Naval fleet of WWII. Beginning with their conversion games produced during the wartime ban, '42 Midway, '42 Arizona, '43 Santa Fe, '44 Idaho, and '44 Oklahoma. In fact the Arizona back box side panels feature a mast with naval burgee pennants flying.
One could easily believe the Utah was also named after a famous battleship, however the post war UMC state machines don't have any obvious graphics which could be attributed to their nautical namesakes. That being said, the Utah, Oklahoma, Nevada, all played significant roles during the Japanese attack on Pearl Harbor. Even the Wisconsin was launched on the second anniversary, December 7th of 1943, and Hawaii of course is the location of the famous harbor (all UMC pinball titles). Given these facts, I believe it's too much of a coincidence to think that the post-war machines were not also namesake homages to the WWII ships. As an added note, UMC kept their very military-looking logo until at least 1960."
