Hello Suzzi - sorry, I can't help either..........I've looked on another 'discontinued' site, but know from my own experience that it can be impossible with many of these designs. It's the older ones that give problems, usually, although as we know yours is a fairly recent design.
Some factories had literally hundreds of patterns - had it been Stuart, we might have had better luck, possibly. Compliments on your photography by the way.
We'll carry on keeping an eye out though.
