help to id Rosenthal pattern

Today I have splashed some cash, 50p to be exact, on this very little Rosenthal bowl numbered 1582 to the rear. Its so sweet,a little song bird but i cant find the pattern.

Any other photos?

I was thinking perhaps a designer of Swedish Norwegian type

Many of their designs came from the UK and unlike UK pottery companies they paid royalties on when designs were used and the number of items sold..... even when designs or part designs were used decades later.
