I am still awaiting the reply from my friend who is not on the internet and also still searching for the photos of Nissa. I have moved so many times in the last few years I cannot remember where I put them.
I've found some not terribly good photos of her under saddle that I could PM to you if you would like to see them. My email addy is: judith.stirling1@btinternet.com if you want to let me have yours.
There was another fab stud in the area during the 80's - Oasis arabian Stud near Southampton. They had a stallion who threw magnificent Chestnuts with coats and colour like your mare. The owners were Laura and Cyril Tiley (sadly no longer with us). Their stallions were Prince Saraph, and Silver Ruler.
She looks a lot like some of the Prince Saraph babies of that era?
I will try sending one without photos - see if that works? Or perhaps its me - I'm suffering with a nasty flu type bug - into its second week now - today I have lost my voice - can only mamage a weak croak!!! I prob pressed the wrong key due to my fuddled head!
My friend in Dorset says they have checked all the photos of their offspring and they do not match. She thinks that your mare may be one of Golden Cavalier's.
I have OH looking for the albums as he put them away somewhere and then I can check the markings on Nissa. If he cannot find them I will go and see her breeder who lives up the road.
