I just had my wifes apart today for a good cleaning. I might can get what you need but what is the ejector shroud?
I'm not terribly familiar with them, just enough to keep hers running since she likes shooting it.
What I do know about it is that it would be simpler for me if I could ever convince her to shoot Colts. But if that's what it takes for me to keep her happily shooting then I'll continue to fumble with the Schofield.
