Welcome to Tool Talk !

First- That is not a pipe wrench, it is a monkey wrench. Pipe wrenches have teeth on the jaws to grip pipe.
Second- Many companies have made those wrenches starting way back in wrench history.

If you carefully clean it, you may find a clue on the upper jaw or on the shank between the adjuster and the handle. It looks like a Coes pattern wrench, once again, made by many.

Let us keep in mind, that pipe wrenches (tongs) did not always have teeth. The early pipe tongs relied on the binding action to grab the pipe. Some companies played off the tong design, and added teeth to 1/2 of the jaws. Then of course Mr. Stillson invented the current version, that has both upper and lower jawed teeth, but still also relies on the binding action as well.
