Found this at an estate sale yesterday and it followed me home - dunno why...
Anyway, it's a six-wrench set held together with a thru-bolt and a knurled thumbscrew.
The largest open-end, 7/8, has a decal, "Penens Corp, 5002, wrench set, formerly #5000n". The box ends are each next size smaller than the open end except for the 5/16 box on the 7/16 open-end. Seems 3/8 would be more appropriate, but??
All are forged with "Auto-Kit No. 100, Mfd. in USA" on one side and "Forged Controlled Steel" on the other. See the pics for the other 1000 words!
Anybody know any more about these?
