Hello everybody,
My first post, I know I should have introduced my self elsewhere but thought I'd dive right in, hope that's OK

I'm a Brit living in Spain & have been gathering/hording/collecting tools for many years in the UK & Spain, at first I wouldn't have known that I was collecting but now I realize..... ahem..... My name is Navaja & I'm a tool collector......there.... I know I'm among people who understand here!
Anyway, I tend to like unusual stuff, old adjustable wrenches through to woodworking stuff but very rarely do I see something I've never seen before, well it happened yesterday-


Difficult to read the markings but I think it reads "PATENT fojore (or fojone) BREVETE" & assume it's French.
I've never seen a wrench like this before, anyone else? Made to grip in one direction & slip in the other, a kind of spring "ratchet" wrench, I think it's so cool but can see why it maybe didn't catch on!
