What do these #'s mean?

Each cylinder is eunuch to the caliber. The 45 ACP cylinder has no cutouts for rims; the case headspaces on the case mouth just like in a 1911 bbl.

A separate cylinder for the 45 ACP. I didn't understand that from the photo. I assumed they all worked in the same cylinder. How does the extractor fit into the rimless 45 ACP on the separate cylinder to eject the cases?

It's a single action revolver. The "extractor" is the little spring loaded push rod under the barrel that pushes the cases out from the open "just fired" side.

That works for me.

Thanks.
