Today I visited a first-class picker and friend, and poked among a great volume of his collected materials. I am a wrench collector, so I had to turn down the very nice 18th c. froe he offered for $65. If any else wants this froe, let me know.
As it turned out, I picked up an 8" Red Chief Mfg. Co. L.G Automatic Wrench, patented Nov. 16, 1915 by Louis E. Gaisser. A push with your thumb adjusts the jaw opening.
The other wrench I found was a Bahco 2A adjustable wrench made in Sweden. The wrench appears to be early, possibly before 1900. The other imprint on the wrench is in Swedish and reads: H. N. TVER=GADE 15.. The wrench is 12" long, and the jaws open to slightly more than 1 3/4".
