Help ID maker--" Auto" pliers

[Lostmind]

I can't make out the name of these neat pliers I've had for many years.

Says " WM than 7? letters , &Co.   Jamestown , NY         Wm. Hjorth & Co. ?

6 1/2" long       late 20's early 30's ?

It's time to pass them on to a new owner , but I'd like to know who made them.
Thanks


I spent some time this afternoon and found this , 1914

I'm confident you've IDed them correctly, Roy; Wm. Hjorth & Co...

Thanks. Not 100% sure they are the ones shown from 1914 , they don't show the ' Auto" in the photo.
I saw a pair on ebay that didn't sell. Maybe not desirable , but neat just the same.

At last the information I was looking for a couple of months back!  Yep, I have a pair of these, too.  Not quite as good condition as yours, but the design of the "Auto" is sooo 1914.  Had to have 'em.  The jaws were what first captured my eye -- look like those on a B&C monkey wrench.  Really sculptural.

Very neat -- much dressier pliers.  Might be more desirable if people knew their age.
