I've had one of those hanging on my torch cart since the 70's.It was pretty useless as an adjustable wrench,but to change the bottles it worked fine.I can only use it on the oxy bottle now,the acetylene bottles no longer use caps.They have recessed the valve down inside a welded on guard.That wrench is too big and gormy to reach down in there at an angle.A modern adjustable won't even do it,I have to use a 1-1/16 open held down at an angle.I have a few of those hanging up,some have names cast into the handles.
