I find it interesting that everyone assumes that all droplocks have doll's heads and C-type top bolts. My droplock, made in ~1949 has a Purdey bolting system and a normal Scott spindle. It also has a filed rib and double triggers. It is lovely. My only gripe is that it has 26" barrels, but I am quite happy with it. Ted, is correct about breaking a striker since I suspect the cost would be killer. A new set of locks was quoted at 3500 pounds.
