I also neglected to mention that the ejector will have a roman numeral two (II) stamped on its left side. The hammer should have a '2' and a 'D' stamped on its left side as well. The 'II' and the '2' indicate the second series ejector and hammer that was introduced very early on in production to resolve a reliability issue. My understanding is that these parts were retro-fitted the earlier production as - when - possible as well.
