Truman -- In my moderately extensive experience with vintage equipment of that period, I've never perceived any particular similarities between Knight amplifiers and those made by H. H. Scott.
Information on, and pictures of, the Scott stereo integrated amplifiers of that time, including the 222C, can be found here:

Best regards,
