I've added 2 more pipe jaw inserts for adjustable wrenches that are in the Coes style. I have a few others that I have posted previously, these are the latest additions. T. C. Page patent number 51,961, Patented January 9, 1866. As with the others I have they don't show very much wear. I guess it was a another one of those great ideas that never worked as well as it appeared it would.

 Those are in beautiful shape. In all the years and boxes of rusty tools I've pawed thru I don't remember ever seeing a pair. (of any maker not just this one)

What was Page, a wrench maker or a wrench parts maker?

Not sure what Page did. Several listings in Cope's book under Page but not this guy, DATAMP states Cope's lists J. W. Storrs & Co NY N. Y. as a possible maker or agent for them and an ad listed in 1870 Scientific American. This was the first patent for a removable pipe jaw insert for wrenches. These have tapered pins that hold the insert in position.

I've never found any in the wild, either.
