Most Lefevers came with extractors, ejectors mainly on the higher grade guns, F thru A. Without pictures or a better description it is hard to know what you have. If it does not have cocking indicators, two small buttons on the side plates, it is probably a DS grade.If the top rib entension is rectangular in shape it is a DS, if the extension is rounded it is called a dolls head, and you probably have a G or H grade. The grade is usually stamped on the water table of the action.!^ and 20 guage guns are rare and most were in the DS grade range.
