Ok, so what tool was used to cut this profile? It definately feels like it was made by a chippy with a good set of tools rather than produced by a bespoke workshop.


From left to right; small flat section, wider flat section, R30 curve and another R30 curve.

Flat areas I'm guessing a planer or perhaps a router but the R30 curves seems too big for a router; wouldn't a 60mm diameter tool just tear itself apart at router speeds? If not a router, what tool was used?

That'd be a big router cutter, I don't think I've seen a coving bit that big, but that doesn't mean to say they're not available. It'd be used in a table with reduced speed. Not freehand.
Probably done on a spindle moulder, possibly with two passes for some reason, from the "nib" that is visible.
Or if it's an old piece may even have been produced using a moulding plane.
 
or theyve done a 'norm' and set the blade in the table saw,and cut across it at about 45 degrees,search youtube.
 
I'm just seeing the one curve on your image. Unless the trees are hiding the sticks.lol.
Whitehill TC convex profiler mebbe.

Running my finger down it, there's a definite ridge and looking closely it looks like two cuts at R30. When I put a R35 profile against it it doesn't quite fit. Having said that, I wouldn't rule out some warping and multiple layers of paint.

Just curious how it might have been made that's all.
 
If it is old and hand-made then it would have been worked by sawing/planing a rebate then forming the rounded hollow by using a large hollow plane
