This wrench was invented over a 150 years ago! It hasn’t changed much over the years because it works. This Walworth Stillsn 18 is somewhere wrong the 1900’s from my research. Beautiful tool and we last 100 more years or more.
That is a thing of beauty. Far to pretty to use now. I think at its age, it deserves a home in that nice display case under the window. Take care and God Bless.
