Vintage Navajo silver Salt & Pepper shakers

A pair of nifty stamped silver Navajo salt & pepper shakers.  These were in the collection of an employee of the Fred Harvey Company.  The lids of each are drilled in the form of an “S” and “P.”  The lids fit well.  Each shaker measures 1 3/4″ tall x 1″ wide.  Marked on the underside, “T K W.”  In very good old condition, useable!
