I picked up one of those Cougar 3/8" SAE sets many years ago as well, to add the ratchet to the obsess... er, "collection". Unfortunately the ratchet itself doesn't have a USA COO stamped on it (a rather critical requirement to keep in the collection, with only a couple very specific exceptions), so out of the drawers it came. The set gives off a strong Stanley vibe to me as well, which also causes me to question the actual COO of the ratchet considering Stanley's checkered past with the FTC.
Interesting that the ratchet in the Wright Allied set has a USA COO stamp but no brand stamp. And the ratchet reeks of Stanley too. Back in the day there was TAT (Thorsen Allied Tools) which were very clearly imports.
