163,522 in Canadian Patents Database
Description:
The focus of the patent is the rounded head, with catches for the chain which make the wrench operable in either direction. The patent elements shown in the Canadian Patents Database show the name of Hamblin's London patent attorneys.

As noted in the DATAMP entry for corresponding U.S. patent 1,104,730, an April 1922 announcement from the Hamblin Tool Mfg. Co. of Newark, NJ may reflect production of this wrench. In the absence of an illustration or actual example, the connection is speculation.
