Numrich is the only one I have ever seen. If I am not mistaken, that is from Kolar/Remington originally. Kolar still uses those numbers for reference on the parts list though some are not available. Numerich has the number parts list for that schematic above, or at least they used to. Kolar still uses some of these springs/parts in their guns today.
What I was hoping to see was the blow up of the ejector.I want to clean it out and I am assuming the little allen screw removes and the round disc is the only thing that retains it.
You are correct. Remove the small Allen pin screw that holds the disk in place. Compress the ejector so the disk aligns in the rounded out area and lift the disk out. Sometimes you can turn it upside down and it will fall out, but not always. Then slowly allow the ejector to push out past the spring compression.
