Indeed it is a pear - a pendulous willow-leaved pear, Pyrus salicifolia 'Pendula'
Note: They are susceptiple to bacterial canker. My one got it. The main lesion almost girdled the stem - which would have killed it. As it happened there were a couple of suckers rising from the rootstock at soil level, and I was able to inarch (a grafting technique) one of them back into the trunk, bypassing the lesion. The graft took, boosted the tree's vigour, and the tree recovered. It developed a sort of keyhole through the trunk as the two parts continued to grow.
