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 NEW TYPE PATENT No. 144034 G.TAYLOR (6) Ld MAKERS BOLTON MADE IN ENGLAND (reverse side): FERRIER & LUCAS
Any information that could point my research on this patent in the right direction would be appreciated.
