I am hunting for those experts on the Win. 1873 44/40. Mine is a third model SRC. I haven't loaded a shell yet, but did take her apart for cleaning and to learn its cycling strategy. Two questions; 1. Its had its' saddle ring replaced with screws and then polished down (an excellent job of polishing) but I would like to return her to her original state. How hard would this be? I don't think it can be done without drilling the screws out. Any sugestions? Thanks in advance for any advice.
