Mission or Arts & Crafts Cast Brass Entry Doorplate

This is a very heavy old brass door plate that was probably manufactured around the turn of the century.  The design is quite handsome with a rotating keyhole cover to seal out drafts.  The brass has weathered to a grayish color with splotches of light colored verdigris.  It does have some scratching commensurate with its age.
