The shape of the receptacle is right for "Glendora," i.e. it is small and narrow, but the rest of the characters don't match. I don't think it's "Glendora."
Here's what's different.
1. "Glendora" blooms in clusters of up to 7 buds. Solitary blooms are uncommon.
2. The foliage on my plants is more rugose and coarser, without rounded points, with lots of 7-leaflet leaves.
3. "Glendora" is famous for producing many (but not all) quartered blooms that reveal a pip in the middle. The quartering is distinct, with the petals lined up and stacked on top of one another.
4. Almost all the sepals have little leafy appendages.
5. The flowering laterals have lots of longer, very sharp, straighter falcate prickles within 2 leaves below the blooms.
6. The armature on the canes basal canes consists of thin, tan, sickle-shaped, slightly down-turned prickles.
7. No where on "Glendora" do I find any wood like that which appears on your shot of the stipule.

Here's an old, faded shot showing the clusters of blooms, the shape of the bloom, the coarse foliage, and the appendages on the buds.

I grow Rose du Roi (supposedly the true one, a reversion from the striped sport Panachée de Lyon), and your rose is not it, either, altho it's close. Rose du Roi has receptacles that are covered with glands. This enormous file was shot to demonstrate macro mode on a camera, so I apologize it's so large. It does show a bud of Rose du Roi.
