Here's Patrick Arnold (of Balco fame) telling the Arnold Calf Implant Story on Misc.Fitness.Weights back in May 1996 -
"Arnold had no calves. Then he went to visit his friend Reg Park in South Africa (where a certain prominent cosmetic surgeon happened to have his residence also.) He stayed a couple of months. The only pictures of him there were of him in Reg's pool with calves underwater and such. Arnold comes back to America with huge calves. Coincidence? When questioned about his huge gains in the calf department, Arnold claims Reg taught him to train them heavy and that this was the 'secret'. Well, for the rest of us heavy calf training does not give anywhere near dramatic results. Am I making this up?
I was told this story by a certain renowned plastic surgeon who goes by the initials B.N., who, though he admitted there is only circumstantial evidence, certainly is qualified to spot such a thing. "
---------------------------
It's the same version Duchaine told, except for Duchaine adding the "small silicone injections" part as how it could've been done. I'm guessing the "B N" is Bruce Nadler, who was a famous bodybuilding plastic surgeon years ago. He'd be involved in a murder - suicide with his wife in the early 2000's, so if there was more to the story, it's gone now.
To be fair to Duchaine, etc....., he usually never told it as fact, it was just one of those pieces of bodybuilding lore that floats around.
Have fun with it

Edit - Duchaine and the silicone bit in 1996, discussing it vs Synthol (not in relation to Arnold, but how the technique works) -
"Why bother with an oil?
The same size needle would pass silicone and it would be safer and last forever. Small injections would allow the body to naturally encapsulate the silicone so it will stay put."
