The photograph is not very crisp but as far as I can see, the corners of the outer (frame) moulding are very sharp. This does not look as if it was cut as a single panel as you cannot machine sharp internal corners like this with a router. You can see this in cheap doors made from a single MDF panel - the internal corners are rounded. The frame was probably made from four components and the moulding machined before assembly. I would guess that you could probably match the moulding shape with a commercially-available router bit but it's a matter of ploughing through cutter catalogues to find a matching profile. More likely, the mouldings were cut on a spindle moulder which gives you access to many more moulding profiles, but we're moving away from the CNC area now!
