I found this 1 hp Delta motor for sale locally. The 84-910 shows up in the catalogs from 1943 to 1958. Prior to 1943 the motor was called a 64-910.

In 1945, Rockwell Manufacturing Company acquired Delta Machinery and named it the Delta Power Tool Division. Rockwell moved the plant from Milwaukee to Bellefontaine, Ohio, in 1953. So this motor was likely made between 1943 and 1953.
