... huh. all very curious edler. I was shown that Taylor jersey I mentioned above by a senior employee at the HHOF, it wasnt on display, had no number & I was told it had been game used. Looked like it as well. Im not convinced the PCHA did use numbers on their jerseys for the entire history of the league. Its my contention it was short lived. Probably because of player turnover, the numbers just adding confusion to the fans. Cant prove it but then I havent seen any hard proof that numbers were used & indeed was shown hard physical proof that numbers were not used. Cant imagine the SIHR would screwup on that but what longevity, length? For how long did they use numbers? Possible the jersey I saw was a practice jersey, a 2nd, a fake. Do I believe my lying eyes or the SIHR?
I dunno. SIHR dosen't list any sources for those numbers, they're only listed for players season-by-season in the team stats section.
As for the PCHA, players on the Seattle Metropolitans
are listed with numbers from season 1917–18 until 1920–21, some players without though in 18–19 & 19–20. Players on the New Westminster Royals, three PCHA seasons between 1912–1914, aren't listed with any numbers. Same for Portland Rosebuds, four seasons between 1915–1918. Victoria Aristocrats
are listed with numbers for the inaugural 1912 season, like the Millionaires, but then like the Millionaires they're listed without numbers for many seasons to follow. Three players on the Aristocrats reappear with numbers in 1918–19, Tommy Dunderdale, Lester Patrick & Bobby Genge, and then in 19–20 most players have numbers, and in 20–21 it's only three players with numbers. In 21–22 only Frank Fredrickson.
It's probably hard to find extensive evidence or proof for player numbers going that far back. Players aren't usually depicted from behind, where numbers usually are put. In the papers, not a very lot of clues. I've done some extensive newspaper & contemporary hockey guide research on the American Amateur League for example and the only player I've seen mentioned with a number in that league is Tom Howard, Jr., in the 1916–17 season, with #13.
