Ray, I just noticed your post. At least 15 years ago, at HomeGoods, I bought a couple of enameled cast iron casseroles branded Nomar and manufactured by Staub. There were lots of them available, so I think Staub must have been closing out the Nomar-branded stock. My pieces are comparable in appearance and heft to the Fontignac casseroles that Bed Bath and Beyond carries, except that the Nomar interiors are matte black instead of glossy beige. As far as I can tell, there’s no difference in functionality between my Nomar casseroles and my Le Creuset ones. I did notice that on the Nomar (and Fontignac) pieces, compared to the Le Creuset ones, the walls of the pot join the bottoms at a sharper angle, but that’s not an issue for me. I don’t know if this adds anything you didn’t already know, but I can certainly validate your own observations!
