In a large bowl, combine 24 cooked and peeled rock or bay shrimp and 1 cup of white wine vinegar; refrigerate for 30 minutes. Meanwhile, in a food processor, blend the yolks from 12 hard-boiled eggs (halved whites reserved), 1/2 cup of mayonnaise, 2 tablespoons of dill pickle juice, 1 teaspoon of Old Bay seasoning, and 1/2 teaspoon of salt until smooth. Drain the shrimp and set them aside. Distribute the filling among the reserved egg-white halves and sprinkle each with a pinch of Old Bay seasoning. Top each deviled egg with a pickled shrimp and a sprig of fresh dill. Serve immediately.
