I have Girard Standard, Girard Special, and plain Girard wooden-handled wrenches. This 5 1/2" nickel-plated Girard Bicycle wrench is 1/4" thick.
That is a nice one! I have Girards, but not one of those.
I get jellies every time I look at the wrenches you post... It would seams we have almost the same tastes in wrenches...
