My husband’s Great Grand Uncle, Charles Albert Prince was sentenced to two years jail for taking part in the Redlock-Erbie ring-in, South Australia, 1934.

from page 119, Ringers & Rascals: A Taste Of Skulduggery, by David Ashforth.
Prince served only five months of his two-year sentence, thanks to remission to mark a visit by the Duke of Gloucester. In 1954, when he was 60, he had further cause to be a royalist. To mark a visit by the newly crowned Queen Elizabeth, the South Australian Jockey Club lifted Prince’s life disqualification.
The mischievious looking Prince told The Sun, a Melbourne paper, that he was happy in his job, working in the bar of a hotel in Violet Town and growing vegetables.
“I made a stupid mistake in helping to ring in Erbie as Redlock,” he confessed. “I hope that nobody else will be as silly as I was and try to get away with it.”
It was a vain hope.
