Steve: The Lefever is really a box lock with side plates. Below about SN# 25,000 I think it is, the sears are attatched to the side plates. The hammers etc. are all mounted in the frame. The cocking indcators are mounted in the sideplates and work off a tapered section on the hammers that push them out when the hammers are cocked. After that range of serial numbers the sears are mounted in the frame also which means they are a box lock with side plates for access to the lockwork only. Your DS is a later gun and would be of this configuration. The DS and I were the lowest grade made under the Lefever patents and were the same gun. The I grade was a branded name gun for Shoverling and Daly and some other "hardware store " private brands. All in all they are still a Lefever and you can expect to see almost any combination of features that may or may not be cataloged. Love it to death!!!! Lee
