Wrench for Wiss "Facile" Screw-Bolt

Wiss wrench. I stumbled upon this picture in 2003. It made no sense. I saved the picture. I've now found in the 1925 through 1937 catalogs that shears fitted with the Wiss "Facile" Screw-Bolt had a small wrench furnished free to adjust the tension. This must be one of them. This bolt was discontinued by 1941 and in 1916 the bolt existed, but the wrench was not offered. See 1934 catalog: page 14.
