Wrench by Penens Corp.

Here's another obscure name in wrench manufacturing.
 Penens Corporation of Cleveland was acquired by Proto Tools in 1942, and postwar the word Chicago was added to the tools. The Penens name continued to be used and in the 1950s produced wrenches under the Fleet Quality brand, ratchets and sockets under the Socketeer brand. 
Before the acquisition there appears to to be little information online available on the company or their tools.
