When you take a Lefever apart, either an ejector or an extractor, it matters not if it is cocked or uncocked. By 1902 there were no parts except the socking indicator pins attached to the side plates. The side plates are covers for the lock work, not just "Falsies". Removing them exposes all the inner works which are attached to the frame rather than the plates. The parts in the gun occupy much the same positions of those in a bar action sidelock, just attached to the frame. The V mainspring lies in a cut in the frame bar just as on the bar action SL. On the in-frame ejectors which I feel sure this one has the upper leg of the spring fires the ejectors & the lower leg the hammers. I can't recall that I have ever run across an easier to work on hammerless double than the Lefever. With the exception of that cocking shaft Roundsworth mentioned there's not much you can actually put together wrong.
