   Quarter round and roman ogee with a couple of fillets. The picture on the right shows it much more clearly than the one on the left, with the domino.

   It's not old. It looks like the blank for the moulding was glued up from 3 pieces.

   If you are hoping to find a router bit to cut that in a single pass you may be out of luck. Without knowing specify radius and other dimensions it's impossible to give specific advice. I would start by looking at some raised panel cutting bits for the large radi profile and then a couple of passes with a bead cutter might be a good start. Success would depend on if you are looking to have an exact match to butt to original molding or can get by with a reasonable facsimile.

   Garret Hack had a good article a few years back on custom molding..

   I have never seen a bit that could do that profile, but suspect that the ogee may well have been cut by a single bit, perhaps a shaper.

   You could get close to the profile by using a stepped roundover bit, a core box bit (both I suspect 1") and a table saw. You would have to make a jig to hold your blank at an appropriate angle.

   A closer match could be obtained by cutting the cove and lands with the core-box bit and table saw, then using a block plane to shape the roundover.

   Someone already said it. That's a Roman ogee fillet profile. They make them.. try Amana tool.. If your trying to come up with an exact match and it isn't available dimensionally as a router bit the easiest but not exactly the cheapest is that a mill works shop can take your profile and grind an exact matching cutter then make you as much as you want. Economically its a good way to go if you want a lot. If it's for something historical or valuable then maybe cost is irrelevant.
   But to answer your question....
   Could you take a beading bit and maybe a cove bit and replicate that?....maybe, or is it going to take a beading bit and maybe a corner rounding bit of a different diameter then maybe a couple different coves ,then....? I've done stuff like that with router bits trying to replace a bit of missing trim on old furniture . It takes multiple passes and lots of trial and error and if you want an exact match it can take a long time..and in the end you might find that you couldn't get it exact. I've had better luck and it's probably faster using hand planes, scrapers and carving tools for small amounts.
