SLI was based in Incline Village, Nevada. They offered Chairlifts and Gondolas
and were known for their maintenance free bail chair. The first 4 pics show a
4 page SLI add in a 1970 Ski Area Management magazine. The next 4 pics show
The SLI gondola design. The first is an add from 1970, the next 3 were
from an ebay auction run in 2000. This Gondola was located in Idaho for sale.
Anyone know where it was originally installed? If you do please email!

Pictures of Sli chairs are here.
