The Thorsen socket posted by oilyrascal made me remember the plug wrench I had. It is a Blackhawk number 4.151 and has four way inside/outside adjustable head. i have used it on everything from a 1930 Ford to my 67 and 79 Jeeps. Very useful and I have not seen any others at flea market or auctions. Wonder if they still make them????
I've been in a lot of repair garages , never saw one. Looks like a must have tool for a lube guy.
thanks for posting it
You would think Sears would have one. They've copied most every other old wrench.

I have a Blackhawk four-way wrench similar to that, and I've seen several similar tools from other manufacturers since I got it; some are two-ended, others also have four ends. I'd have to look more closely at mine, but I didn't think that it had such a coarse thread as the one shown.
