I remember him well. He was born at London Zoo in 1995 (?) to a truly hopeless female called "Mira" who was genetically important but had the maternal instincts of a cuckoo.
Harri was pulled for handrearing after his mother had been observed chewing him. As it was she managed to chew off a couple of toes as well as the damage to be seen here.
Nice to know he's still around. His father "Martin" (ex-Thrigby, ex-Rotterdam) was a magnificent beast; it was a great pity that he was never matched with a suitable mate at London.
