How old North American chair at Mt. Norquay?

[Jim Kenney]

Anybody know how old the North American pulse double chair is at Mt. Norquay outside Banff, AB? It's a pretty neat lift in a historic sense and serves challenging terrain with great views of Mt. Rundle. They've been skiing there since the early 20th century, but I think this chair is from the 1950s? I can't find definitive info on that though. Thanks.

Sorry, I guess I should have done a bit more googling before asking my question. This link indicates - "Our first ski cabin was built in 1927 and the first rope tow was installed in 1941. The North American or “Big Chair” has been providing riders with views high above the Bow Valley views since 1948, making it one of the oldest chairs in North America."
