Searchin' for my lost shaker of salt

I have this salt shaker that I found in my house when I moved in. It was one of the few items that I kept when I cleaned out the kitchen cabinets. For two years I have searched on eBay trying to find a match so I can use the set. It reminds me of a miniature sugar shaker with the fluted sides and flared out base. I had hoped to have found a clue with any markings on the bottom but it only has "made in china" and 15 so no luck there. Maybe one day I will stubble upon its mate until then it lives in the spice cabinet.
