Big Railroad Wrench

[john k]

A truck was in the shop for service, a RR car maintenance vehicle.   The tool boxes were standing open, in one was this steel wrench.   Note the two jaw sizes on one end.   No idea what it is used for, but in the truck was also a bundle of brake shoes, and a very heavy equalizer bar looking item.  .............okay, pics are not posting.  The end with the double size jaw was about 2 inch  and 2.5 inches.  The other end was open end set at 45degrees, about 2 inches also.   Wrench was about 33 inches, and was flame cut from 7/8 steel plate.  Was finish ground, not a crudely made shop tool.
