Sorry, but I don't do pix. But its design resembles this one, though the markings are quite different.

In the recessed handle panel: NO.474 ADJUSTABLE SPANNER WRENCH
Opposite side: J.H.WILLIAMS & CO., BROOKLYN--BUFFALO, U.S.A. followed by diamond W logo
Stamped outside the panel: SPECIAL FINISH
It does not have the Williams underline logo, which was introduced in 1924, and mentions Brooklyn, as well as Buffalo. AA states that Williams moved some production to Buffalo in 1914 and completed the move in 1919. So, I assume it was manufactured between those two dates.
It has no owners' marks and seems to have no finish at all, but a nice patina. Very few scratches, and really no sign of use at all on the jaw area.
Oh, and if anyone has a spare $349.99 I will entertain your offer quite favorably. ;-)
