The jaws of this brace fit the chuck and its shell, but they are so-called Barber's Improved, first made by the Millers Falls company, then by Charles Amidon's later companies, and used here by John S. Fray & Co., presumably after the Amidon patent (U.S. Patent No. 73,279, granted January 14, 1868) had expired.
What you see here is exactly what appears in Fray's Catalog No.26, 1911.
Everything about the brace is functioning well, with only the 50% lost nickel plating to mar its appearance. It's not peeling very badly, though.
