Or would the New Britain be a "copy" of an SK design?

From "Alloy Artifacts" -
"In the early 1950s New Britain licensed a patent for a new ratchet design that promised great strength in a very small head. The ratchet design and a later improvement were developed by Luther Kilness, and the patents were issued as #2,554,990 in 1951 and #2,981,389 in 1961. These are basically second-generation improvements on the original round-head fine-tooth patent #1,981,526 developed by S-K's Theodore Rueb in 1934.
The Kilness-design ratchets were highly successful products for New Britain, and probably should be considered as one of the company's most important contributions to tool development. The Husky product line included a number of models based on these patents, as the following figures will show."
