I wear a star and the number 3. No marks on my back. Who am I ?

Cute but no idea.  Looks like one for Bus.

you are jimwrench

There are several other wrenches similar to yours both marked and unmarked. The marked ones include: Posch, Cleveland Faucet and Berner-Mayer. These three companies had something to do with beer dispensing equipment. So the star wrench may also be a beer tap wrench.

 Thanks Amertrac, at my age identity can be a problem.
Thanks Bus being a teetotaler beer dispensing equipment is out of my experiense range. Did find a similar wrench in Mar 2006 page 2 of MVWC newsletter. It was marked (Franklin) and probably had similar usage but was not identified at that time.

Jim;

The Franklin wrench in MVWC newsletter is mine.  It's down off the board now, headed for the melt pile as no one has ever been able to identify it.

Don't melt it!  If nobody else wants it, I'd like it.
