You may be right (and according to an earlier post above, you almost always are!)
Given the probable absence of a manufacturing code...is there any way to guess at an approximate manufacturing date for these pliers?
I acquired this set of Craftsman Linesmans Pliers several years ago from the estate of an older gentleman who had a large collection of Craftsman tools. I was told that most of these had been purchased between the 60's and 80's.
These pliers are 8-3/4" long. The grip coverings may appear...
