Master Salt Cellar made by Baccarat and has the Company's round logo on the bottom of the sparking crystal piece. This mark or logo of Baccarat pieces just started in 1937. Before that items were numbered. In excellent and pristine condition, I can't tell you the age but after 1936. No chips or cracks but very minor scratches on the bottom. Gorgeous, clear crystal glass, and nothing says "elegant" like good crystal. The master salt cellar is 5 1/3" wide and 3" tall in the center. Stunning! You could use this to put salt on one side and pepper on the other.
