This ten-inch swing brace has none of its original nickel plating, but there is now a rich blue-black patina on the smooth steel and iron.  The Robert Ellrich patent ratchet housing has the patent date faintly stamped on it, and another Ellrich patent, for a different chuck, is stamped clearly on the bow.  The actual installed chuck is the Peck & Powers style instead.  The quill has ball bearings and is original and fully functional with a rosewood pad.  No apologies.

Here is that boldly stamped patent date of May 17, 1892, for Robert Ellrich's patent chuck, which isn't what's on this brace !

The Robert Ellrich patent date of February 19, 1884 for the chuck is stamped as shown at right on the upper reach of the bow, but missed the mark.

The rosewood wrist handle is in good condition.
