Post World War II German Made Traveling Cocktail Set from the US Zone

A traveling cocktail set with a leather case, the stitching on the zipper is partially unstitched. The straps are missing. But the leather overall is in good shape. Inside are the 2 shakers, 5 cups, 4 spoons, one lid and the fittings for all the pieces in the case. The spoons stainless steel I think and are made by Rosterei a well-known German manufacturer of silverware. The cups and shakers are marked Made in Germany, US Zone. I did not see a manufacturer. These markings indicate it was made right after WWII.
