From my Grandfather's toolbox, this is a set of (3) Vintage Kastar SAE Ignition Wrenches. Each is marked, "MADE IN U.S.A." with the Kastar logo (circle with star inside, "K" in the center). These particular wrenches were sold as a set by Kastar.
Includes:
13/64" x 15/64" marked 'A'
7/32" x 1/4" marked 'B'
17/64" x 19/64" marked 'E'
Plus, a BONUS vintage 1960s wrench:
9/32" x 5/16" (Japan 'Quality Steel', see photos 1,3,5)
All are in good vintage condition. Some marks visible from use. A nice set of tools for the vintage auto enthusiast (or if you just have an old car)!
Cash Only, Local (Cincinnati-area) pickup.
