My last guess is Perdita.
The mix of colors really suggests an Austin rose. Sharifa Asma as depicted on 192 of Clair Martin's 100 English Roses for the American Garden has almost exactly the same coloration.
Almost as close is Perdita as depicted on p 170 of Austin's Old Roses & English Roses. Botanica's Pocket Roses depicts Perdita as a pale apricot rose exactly the color of your second photo and it suggests that fall blooms have noticeably more pink, as your first.
Troilus has the same yellow coloration, (Martin, p. 238) but no pink. The problem with asserting that it is not an Austin rose, it seems to me, is that the pink and yellow shading are not found together in gallicas or hybrid perpetuals - the old roses with this sort of cupped form. And if any do exist, all of the HPs that RVR sells are distinctly pink, crimson, or white, with not yellowish shading.
Teas, hybrid teas, and the roses that descend from them including floribundas and David Austin roses sometimes do have pink and yellow coloration, but the cupped form David Austin declares as a defining quality of English Rose, even in the case of Gruss an Aachen - which I think is not quite cupped enough to match the second photo.
The only class that has both the cupped and muddled form and the mix of pink and yellow is the DA rose (or possibly same style more recent hybridizers). RVR does, indeed sell Perdita and Troilus, but not Sharifa Asma.
My best guess is Perdita.
