Yes, the jukebox company. Rock-Ola was one of the contractors that built M1 Carbines for the U.S. military in the Second World War, and its rifles are among the more sought-after ones. The seller calls it genuine Rock-Ola production, with vintage wood furniture, and notes that it was imported by Blue Sky.

It is a semi-automatic rifle in .30 Carbine with a 16-inch barrel and a 20-round capacity, and gives the serial number as 45432171. The case is not included. The .30 Carbine cartridge is light in recoil and the short rifle handles easily, so it is as pleasant at the range as it is interesting on a shelf.

Collectors of the M1 Carbine often chase the different makers, since each had its own marks and part styles. A Rock-Ola with a clear maker mark is a good addition. Many carbines were rebuilt over the years, so look closely at the photos for the parts.

When it arrives, check the receiver, barrel, and stock. Test the magazine and cycle the action. Use fresh ammunition made for the .30 Carbine. It is sold as described, in used condition. The rifle ships to your FFL dealer for the background check.
