Inland was a division of GM. Also Frigidaire was GM and they didn't make Kelvinators. Both plants were a little south of Dayton Ohio. One of my shooting buddies has an Inland Carbine that was presented to his Uncle. It is unfired except for proofing. The uncle was the General Manager of Inland. It's gorgeous. My Mother and my aunt both assembled carbines at Inland during the war.
Have a good day
