I've had a private email from North Houston Roses, who had a slight problem in replying to my question for information on "Belmont Yellow". With our grateful thanks to them, and with their permission, I have cut and pasted their reply:

I'll tell you what I can about my plant. I received it just about six months ago as a small sized band. I do not disbud young roses, and so it has bloomed several cycles, but it has been a slow grower. It is currently 6 inches tall by 13 inches wide, and It has been thornless so far. I seem to remember that it does have a slight fragrance, but because I watered it with some fish emulsion this evening, I can't really tell you more about the fragrance right now. The opening buds do show a darkish cream to pale yellow color, but the flowers themselves have always been cream. Perhaps the flowers might be a bit darker if it blooms during our winter this year. There have been two GardenWeb forum threads discussing this rose this past spring :
"Belmont Yellow" thread: http://forums2.gardenweb.com/forums/load/rosesant/msg0215212012349.html
"Schmidt's Smooth Yellow" thread: http://forums2.gardenweb.com/forums/load/rosesant/msg0411342326289.html
The forum threads do sometimes disappear, so I will copy the information given by Ann from Tennessee regarding "Belmont Yellow".

"A number of Belmont roses were found and saved by Roses Unlimited..... I have grown "Belmont Yellow" from RU for over a decade. I expect RVV got theirs from Ashdown when they bought out Ashdown's stock..... My "Belmont Yellow"s stayed short, with wonderful shiny foliage. I had one single bloom sport back to a single and mine seldom made fertile hips. The major difference, though, is that mine never ever were the clear yellow buds nor did they bloom yellow and fade. Mine, color wise, reminded me often of the small gardenia blooms that we see so often as pot plants in the spring. Rich cream fading to paler cream."

Some people seem to think that "Schmidt's Smooth Yellow" might be the same rose as "Belmont Yellow". According to Kim Rupert in the "Schmidt's Smooth Yellow" thread, Malcom Manners has "Schmidt's Smooth Yellow" and he was going to ask Roses Unlimited to send" Belmont Yellow" as well so he can compare them, and perhaps have some students do DNA sampling on them. It is possible that any of these people might now be able to tell you more. I would also think that Pat at Roses Unlimited could also tell you more.

I'm considering this rose and wondering about its degree of thorniness. Thanks for any information!

Best wishes,
Mary
