A related issue. The so-called "Nested Diamond" handle pattern grip was used on many types of pliers, including combination slip joint, dykes, lineman's, and angle-nose (Water pump). But not all the pliers have the Circle-C code. Some have an AM code. Some have other codes if I recall correctly. That can only mean one of a few things:
- Either Sears & Roebuck owned the pattern, and gave it out to multiple mfgrs to use in their dies
- One of the mfgrs owned it, and let other Sears & Roebuck mfgrs use it
- Or the codes are not mfgr's codes (i.e., one mfgr who owns the grip made them all)
Or one mfgr owned the pattern, and made so many pliers they for one reason or another used more than one code., like circleH/BE.
Micing the hinge element of multible same size pliers might give another clue
