The Nash wrench is for a Nash automobile tool kit and is one of three wrenches . They are easy to identify as they are marked Nash 1, Nash 2, and Nash 3.
The Kawasaki wrench is marked with the big K and not earlier logos. I do not have an exact date but the switch to the big K marking supposedly happened some time in the early 1980's. The wrench is probably from a motorcycle, snowmobile or ATV tool kit.
