Can someone with a 39-2 post or send a photo (or link to a photo) of the chamber end of the barrel, particularly showing the extractor cut?

Thanks

This one came up on Google

Excuse the barrel's appearance, please. I just happened to have a "rescue" 39-2 (59 if one wants to be technical, sort of) barrel on my shop bench and saw no reason to clean it before finishing it - which has some distance to go as yet.











Hopefully, these will help. If not, I've got a few more - specifics will be appreciated!

Later.
