Very small chain wrench

Posted these in General Discussion...the chain wrench (lower right) is very small and has not a single identifying mark anywhere.

The green dot Trimo is the cool one.  Those folks made a pipe wrenchy monkey wrench.

I have at least 5 of these similar type wrenches that I call railroad wrenches, up to 18" in length.  They are railroad wrenches because it gives them a descriptive and alliterative name and because several of the ones I've found have been stamped with the abbreviation for various railroads like Erie and Lehigh Valley.  I have a pipe wrench stamped with NY,NH&H - New York, New Haven and Hartford Railroad.
They are very useful for breaking loose large nuts on various cylindrical assemblies, but I mostly use them for bending and straightening metal brackets and panels.  The handles will accept a pipe for increased leverage.

I think it is a cutter, not a wrench.
