Here are additional images of the rose.

The additional photographs make my first guess wrong. The size of the bush is really impressive (as is the health of the foliage).
The redder edges of the petals in the additional photos should be a real diagnostic aid, but I don't think I've ever seen this rose before.

Parade?

Cl. Cramoisi Superieur.

It does have that China rose look to it. HollySprings might be onto something.

Tend to agree: Cramoisi Superieur, an old China. Sometimes the color is more solid and then again sometimes the centers are a bit paler with more contrast. Opens out and shows yellow stamens. Does get a bit of black spot.

Thank you to HollySprings and to the rest for your replies.
I believe HollySprings is very likely correct. By far the closest I've seen. If anyone else has any suggestions, send 'em my way.
Stay cool.
