I saw this one and no way was it not going home with me. It's stamped steel. I have no idea what it's for or who made it. The sizes are 5/16 and 1/2. There are two marks one is a G and B inside a circle and G.W.-1. lauver over at The Garage Gazette suggested Gardner Bender as the GB which makes sense to me.

Any ideas or help would be most appreciated.

It seems quite delicate, like maybe an ignition system wrench perhaps..?

 Schultz shows a wrench that looks like yours and gives Gray of Toronto as maker. Schultz 903.

Nope.  Gilfillan Bros., Inc.  It's a GW-1, a "Special Wrench (case hardened) for changing charging rate on all Ford and Liberty generators  as used on Ford cars."  According to their #9 catalog.

I ought to point out that 1930 sent me the Gilfillan Bros. catalog when I sent him the GW-1 I found last year. 
Now if he gets two of these, he's on his way to making a robot buddy for the little green guy -- two arms, anyway.
