Is this a test?
What I can see of it looks like a small outside corner-round.

I’ve turned these on a lathe mandrel from paper-glued blocks with a hole through the center (just like the base moldings) 4 corners at a time. I once had an 8ft circle crown turned on an outboard lathe faceplate. I’ve also milled them from solid stock on a shaper in stacked milling operations

Radius crown manufactured on-site from alternating strips, ripped vertically from two straight pieces of molding. The strips are applied one against the other and directly to the curved walls or forms.

Finally on large radius application, the crown can be milled in flat arcs. The arc segments are made to equal the base of an inverted cone which is equal to the radius of the desired curve. “Sprung Molding”
