**molding

Tou can likely recreate it with an embossed molding, I found several that seemed like they would work.

I haven't seen that profile in standard catalogs, the vertical "bead" pieces at the bottom are unusual. You may need to use a profile gauge to duplicate it and talk to a custom moulding provider. The top portion looks like a standard WM 47/WM 45, the very bottom piece can be found in catalogs, but that vertical bead section is the unusual part for me.

The picture appears to show a three-piece assembly consisting of a crown moulding, a Federal style reeded frieze moulding and an inverted base cap. Check with manufacturers of period mouldings before going the custom route. I've had good experience dealing with J.P. Moriarty in Somerville, MA
