I'm not up on all of my gunsmith terminology like the rest of you Masters. Looks like I'm the stupid one.

Well Bob, I don't know about your being stupid. You did properly name the convex and concave parts of the moulding.
IMHO, there is nothing stupid about that. While there are nuances to the names of coves, beads, panels, and other areas of gun work, it does sometimes take time to learn all of the the proper names, so be patient, read the various threads, and ask questions about those things you don't understand.
It can, sometimes, be easier to express your questions by posting a photo and asking something similar to " How do I do this"?
God bless
