These non-reversibles were made by New Britain and they were branded/sold as NONE BETTER S-40, Husky 3183, and Craftsman (H). And if you were wondering, that "6-46" forged-in marking is a date code. I conducted a survey back in 2015 of a few dozen ratchets. The earliest reported is a "2-43" and the latest a "10-46". The date coding appears to have been a wartime practice (appears on some of the reversible versions as well) that was continued for awhile after the war, then dropped.
