Gang,

I picked up a nice 10" pipe wrench this morning.  It's clearly marked J.P. Danielson Co. Jamestown N.Y. There are no visible model numbers or patent info.  There is a "10" forged into the lower part of the moving jaw.

I checked AA, but my wrench is visually different than the examples posted on AA.  Mine also has a wood handle, whereas AA examples all have traditional I-beam handles. 

Have any of you pipe wrench collectors/officionados seen this wrench before?  Got any ideas on how to date it?  Any help or direction appreciated.

Here's a few dirty pictures for you amusement:

Yours is near identical with the Oswego 10 inch shown on Alloy Artifacts, and with the Stillson marked 10 inch I found last summer.

Oh, though clearly marked "Stillson" and "Registered Trademark," the one I found was made by WALWORTH MFG C0.

Walworth was the original maker of the Stillson-pattern wrenches; Daniel Stillson was working for Walworth when he invented his wrench...

Gary, I have one very similar to yours; I'll dig it out of the garage & take a photo or two...

Branson & LG,

Thanks for the info.  Any thoughts as to likely date range?

Just curious, what year was "Stillson" trademarked or patened?

Here's mine:





Gary, my notes say "1930s?" so it looks like I never found out anything conclusive regarding the age & I don't even recall where I came up with that guess...

Let me know if you find out!

LG,

Your wrench, although essentialy the same as mine, is different in two ways:

1) yours has depressed panels on the moving jaw, mine doesn't.

2) yours has a reference to the "Stillson Pattern" and mine does not.

The Stillson trade mark app/issue dates my hold the clue to the earliest possible dates for our wrenches. A reasonable starting point.

As a pure guess, I'd say yours is older Gary...
