I had, the pleasure of working with Bindu at Port Lympne back in the mid to late 80,s, he only ever had peg,s not tusk,s. He farther calfs, at Lympne, am not sure if any survived,while i was there Rani had a calf by Bindu but saddley the calf was stillborn.
The only calf to survive was 'Sittang' and he would have been fathered by 'Luka.' Even he died at two years old, shortly before the Asian elephants were dispersed.
