Brace PEXTO-04 - P.S.&W.Co. No.1201.
Price: $15.00 plus shipping.
This twelve-inch-swing brace is in the middle range, as it probably originally had the Whitney-Ellrich patent jaw spring (now replaced with a bit of wire from a nail). It was made after the Ellrich ratchet patent had expired in 1901 as well as after the Whitney-Ellrich patent was sent to the US Patent Office in May of 1910. The ball bearings and the affixing screw are all original, but one of the jaws cracked when I tried to straighten it. Only about 15% of the nickel plating remains, but the steel surface has a pleasant, smooth patina with no pitting. The H.V. Smith patent for the ball-bearing chuck would have expired in 1912.
