I bought this rusty antique monkey wrench with a few euros for restoration. The old tool does not have any markings on it. It had a lot of rust on it and the jaws were not moving properly. The back of the wrench had been used as a hammer so I filed out all the badly bent edges and the surfaces of the jaws. I did not change the handle as it seemed to be in a decent condition and not rotten. It only had one small crack. The end of the handle wouldn't have come off because it didn't have a nut like most similar wrenches so I couldn't just have made a new one with leathe in few minutes.
