And technically all ejectors are only lifters until one or both barrels have been fired. If you have the occasion (or Glenthornite inclination) to chamber and remove shells without pulling a trigger then all you ever see is ejectors functioning as extractors (plural). So doubleguns may have either one extractor or one extractor and one extractor/ejector or two extractors or two extractors/ejectors. Multitasking makes for some strange math as in 1X2=1 and 2+2=2. In any event, extractor doublegun got only one thingy; ejector gun got two.

Presumably the RBL works in this way unless interferred with by all the slobber migrating into the action from the 4X wood. From now on, I'm adopting new nomenclature; unijacker and hemiwhacker sounds about right. This would throw most of my old doubles into the BoxLock NonHemiwhacker category.
