KNOW YOUR PEARS ?

I've come up to the hen run which is right at the back of my property. It is a very large area & fully fenced but, as you know, all my chickens have gone to the big chicken house in the sky. Since their demise it has become very overgrown. From now on I'm going to call it The Orchard. It has several fruit trees, including a Wilsons Wonder Walnut, which has nuts the size of duck eggs, which are a treasure, it is huge but doesn't produce that many nuts. I think I will have to whack it..........isn't there a proverb - "a woman, a dog & a walnut tree, the harder they are beaten, the better they be ?".
Then there is a Moorpark Apricot, a Fantasia Nectarine, two apple trees, Fuji & a lovely Granny Smith.
But I'm stumped because I don't know the name of this Pear tree. I am relying on you dear blippers to help me out ? Any suggestions ?
