Vintage 1930's? Dayton Wire Wheel knock-off wrench. The wrench is stamped Dayton Wire Wheel and has H103A cast into the handle. There is also what appears to be a date cast into the handle... 3 27 36 ? The octagonal opening measures 2-3/4" across side to side. The overall length is approximately 13". The condition is excellent. There is still a good amount of original black paint remaining. This wrench does not appear to have been used. Nice addition to any collection.
