A mate of mine found this adjustable double ended spanner/wrench , it has no markings to show where or when it was made. The tool is about 10 inches long .

It was found in the dust of an old closed down sawmill. The mill ran from around the 1930s -  late 1980s.

Does anyone have any idea of the age or who the maker may of been ? ?

Your wrench was probably made in the era of 1890 to 1930.  Many makers of wrenches had terrific ideas of how to make their tools different/better than what was out there.  Without some markings, it is near impossible to tell who made it.

WOW! That is a very cool spanner!!! :)

That's pretty neat alright, well worth cleaning up and hanging on a wall. I don't know what else to say.
