rough cut it amd make your own scraper to match to finish it up...
QS is a very good plan...
I believe the apron is a log siding profile...
What stick says is the way to go.
I have made a similar piece a few years ago on a cabinet bottom skirt that formed a front leg on the cabinet, it was only about a foot long and split lengthwise and the piece was missing.
You only need a couple of feet of apron, so make it yourself by hand.
What I would do is rip a piece full width, make a template of the profile, and draw the profile on the ends of the board.
On the table saw cut a rebate the size of the bottom bead on the apron. Looks like 3/8"X3/8" .
Run a full 3/8" bead on the router table. It will take 2 passes,one horizontal the other vertical.
Then with a Block plane, scraper, spoke shave,rasp, file,sanding block, what ever is easiest start working the large radius curve on the face. You will be surprised and happy how fast you can work it down to size. It is a pretty flat curve .
My preference to work it down would be a block with 60grit glued to one side and 80 grit to the other, and scrub lengthwise like a plane.
Once you get it made you will beam with satisfaction at doing it yourself.
