I am researching the mechanical development of tools used by Fisheries in the Bristol Bay area.

I'm in possession of a tool marked, "OKILL'S PATENT PRESSURE INDICATOR, NEW TYPE PATENT No. 144034. This was one of the few tools which I was unable to find any information on. I have not been able to find any record of the PATENT NO. 144034 and would appreciate any information regarding this particular model.

Here is the label on the tool:

              OKILL'S PATENT PRESSURE INDICATOR
                            N.D, 528

                         MADE IN ENGLAND
          (reverse side):              FERRIER & LUCAS

Any information that could point my research on this patent in the right direction would be appreciated.
