This 24" long forged old wrench (2 3/4") has the Arm and Hammer logo on the shaft, could it be made by Columbus Forge & Iron Co. ?  The candle holder measures 12" in height.

It's possible, but I don't know if they did any closed die work there. Wrenches like this certainly could have been made by open die methods, but if so, then you'd expect the logo to be stamped in rather than raised as in your wrench. I know of at least one other anvil company (Vulcan) that used the same logo and there is a very famous tool making company (Armstrong) that made tool holder for lathes and similar items. I don't know if they ever used that logo or not.
