The original T-Bar was (from all acounts) a homemade (or local-made) construction, sporting wooden towers. In 1971, the owner of Azu extended the T-Bar to rise around 3/4 of the way up the mountain. GMD Mueller constructed the additional portal towers, leaving the original wooden ones (likely due to cost). A new drive and return terminal was added, sheave trains were all rebuilt, and regular Mueller T’s were installed.
When Azu became Powder King in the mid 1980’s, the T-Bar was abandoned, then removed as the base of the ski area shifted.

Did a bit more research on Azu ski village.
