Ratcheting wrench set from last weekend's estate sale. The 9/16 wrench is a Thorsen Speed-Hed wrench. Alloy Artifacts points out Spped-Hed wrenches bear a stocking resemblance to Vlchek wrenches. The others are Quali-Kraft, a Montgomery Ward tool brand. They were manufactured in Japan. Also, per Alloy Artifacts, the Thorsen Speed-Hed wrench is from the mid 50's making it close to 70 years old. The Quali-Kraft wrenches could be from as late as the 90's.
