I don't own one but I've always wanted a Rock-ola. Just something amusing and yet serious about a juke box mfg. making rifles. Reminds you just how much ww2 changed America, and how much people 'chipped in.'
Out of the 10 prime contractors, only one had firearms experience:
Inland Manufacturing: General Motors Truck parts plant
Winchester Firearms: Commercial Firearms manufacturer
Underwood: Typewriter Company
IBM: International Business Machines
National Postal Meter: Mail sorting machines.
Rock-Ola: Jukeboxes
Standard Products: GM Bumper and trim plant (they were awarded a contract to make M1903 Springfield rifles, but the M1 Carbine was deemed to be needed more and the contract was ammended)
Quality Hardware and Machine: Machine tools and hand tools
Saginaw Steering and Gear: GM Steering gear plant
Saginaw S.G., Grand Rapids. GM Steering gear plant, assumed the failed Irwin Pedersen contract.
Very interesting to see that companies with light manufacturing capabilitys with no firearms experiece were able to successfully produce vast numbers of this carbine during WWII. I doubt this feat could be accomplished as easily today...
