That would be a pity... but still a wonderful rose!
The other characteristics match: The most magnificent bloomer, blooms at the end of the canes in large pyramidal bouquets. Single, bright deep pink with white eye. Magnificent ornamental, good autumn bloom, long stems, upright, 1-2 m., hardy. Rugose leaves.

When I look at the photo of Vladimír Ježovič: http://www.helpmefind.com/rose/l.php?l=21.107315
The leaves and stipules look the same as those of my specimen, except for glossiness.

The sandpaper-feeling is caused by the underside of the leaves. I checked a moment ago.
Mozart at my place has glossier foliage. Although the leaves are smaller than those of Heinrich Conrad Söth.

Oops...
I wrote those older comments myself in earlier stage of the plant.
Than it may have flowered continuously, but in very small sprays and not that abundant/awesome/impressive as this year.

This year, it had lots of fresh wood, due to pruning and it flowered like mad for 6 weeks in a row.
Than for some time there fell no rain and I didn't water at all... no new buds, no roses and no new growth. The plant stayed green and didn't loose leaves. I cut of the sprays of beginning hips to encourage flowering and new growth.
It has been raining now and then the past weeks, I'll see what the effect will be. And report than in case I don't forget!(I'm getting older You know)
