I googled Rusty, and DG and HMF came up. Next time, I'll start here!
Rusty looks like a rose with some mystery! Those photos are quite variable. I would sure like to know the hybridizer and parentage.
The Coral Dawn that I grew at my last house didn't look anything like the photo on here. When I google images for Coral Dawn, I see a few that look like the plant I had. Mine grew over a pergola and was maybe 18' long. It bloomed off and on all summer, into the fall. The flowers were not pure coral, but a coral-pink blend. It reached the bedroom window on the second floor. I wouldn't call it a large-flowered climber, either. It had small perfect buds, like a sweetheart rose, but a bit bigger. It had a metal J & P tag with the name. I bought it in 1998. I wish I knew what it really was. When we put the house up for sale, I started taking cuttings, but never got any to root. I would say it was the color of Climbing America. Wonderful scent. No disease. It wasn't terrifically hardy, because two different winters I thought I had lost it. It grew new long canes each spring. After 8 years, the trunk was as big around as my arm, and there was no way I could dig it out. Any guesses on what I had?
