In the interest of helping fellow Galoots identify the wrench from the Yankee
Radio Tool Kit, I’ve extracted the following from the web page you proffered:
“Wrench - one end 5/16" square/hex - the other 1/2" hex for jacks.”
From the illustrations and photos, it appears to be a stamped-steel wrench
The hexagonal end has an offset bend.
I’ve never seen one of these that I can recall, but of course the Porch denizens
will now be keeping an eye out for them on your behalf.
If my description is faulty, please post a correction.
