HubertG - Thank you for the suggestion but I'm not convinced my mystery plant was descended from Prima Ballerina.
According to the 'Rosebook' web pages, Paris Charm has solitary blooms and also clusters of 5-7 but my mystery plant only had solitary peduncles or up to 3 together, each peduncle about 5-7 inch long, light-green and fuzzy. The growth supporting these was painful to handle (without gloves) and the two main woody, prickled trunks from the ground, together with the top-growth, reached up to 6-feet and more. I have since been informed that the plant was a climber which in other years went up over the little shed roof but at the times I harvested its flowers, the plant had either been trimmed down or hadn't grown back fully from a hard pruning in the previous Winter.
Though the mystery plant definitely looked 'familiar' like many a coral-pink hybrid tea climber, it was at least comparable in form and colour to something like 'Touch of Class' but with smaller and neater blooms.
The beautiful, uplifting strawberry/rose/mango aroma was more pervasive (in the vase) than my Chandos Beauty, Special Anniversary or even Memorial Day - possibly because each petal was quite thin in substance and the scent production organs and glands may have been more developed than in most other kinds of rose.
