Can't find any threads on him? Apparently this guy went 222 (227 on his Boxrec page) bouts in all without once being stopped? Rock chin or great defense? Says he boxed, debuting as a lightweight, from 1906 - 1929. Seems he boxed quite a high level of opposition, including a young Jack Britton several times. Anyone got info? https://boxrec.com/en/proboxer/119611?offset=0
Harry Stone, known as Hop Harry Stone because of the way he delivered his punches, fought extensively in Australia where he arrived in 1913. The Australasian Boxing Record (1924) accredites him with almost 250 bouts at the time of his arrival. He was absent from Australia from January 1914 until 1916, fighting in England and America during that time. According to researh by Barry Hugman on his History of World Championship boxing Stone was a claimant to the Welterweight Championship of the World between 1914-1916 Stone, of Hebrew heritage, had a very extensive career. He is reputed to have fought over 500 bouts before retiring. Stone in the over 200 fights entered on boxrec has yet to have a recorded KO or TKO loss--he is only the second fighter in boxing history to have over 200 recorded fights without ever suffering a K0 or TK0 loss, the other was the great Benny Valger!
https://trove.nla.gov.au/newspaper/article/49577803 Is a good read, says he had over 500 fights, confirmed that he has never been knocked out (nor DQ'd, must be the gentleman type). Lots of other info too Seems like the type that lost whenever he stepped up in competition sadly.
