Brake Wrench for Lockheed Beakes
Catalog drawing and the actual tools
The C series replaced the C series and are standard open end wrenches with 15 degree angles on one side and zero degree on the other side. They are marked Blue Point. These existed in the 1937 and 1948 catalogs, but it is likely they existed well before 1937. I know they were not in the 1953 catalog, so between 1949 and 1952 they were dropped. They were Ignition Wrenches
Designed for ignition, carburetor, radio, and other tiny assemblies.
In the photo, the catalog drawing is shown and the set is below. I have a collection of tools and the bottom photo shows the variations (In the order I think runs earliest to latest) in the labels. There are no date stamps other than the last one is stamped 1954. This is outside the listed range
