i did a bit of research and found this out........
The Royal School ring-in
While the Fine Cotton affair was low-tech, the Royal School scandal at Casterton, western Victoria, in May 1972, was meticulously planned. Owner Rick Renzella, a former used-car salesman, bought the gelding for $350 with a view to a ring-in. The main problem was that the horse that ran in his place at Casterton won with ridiculous ease. An inquiry revealed the winner to be Regal Vista, who had won the 1970 Liston Stakes at Caulfield. Renzella was jailed for two years.
i rang my uncle up and he cant remember that much but his mate that we went with had 50ew at 66to1 and that was a lot of cash back then and i do recall them getting ********ed as that night
