The Li-4:

The Li-4 was a 4 engine piston Airliner originally developed from a military transport and which proved to be a successful airliner during the travel and passenger boom after 'the war' and until newer models, specifically jets, could replace it.
The Li-4 sold very successfully to many large and small airlines which were in need of larger and longer range airliners to replace pre-war ones, and served them well for many years.
Most Li-4s have been retired from service, with some specific examples still flying on special occasions and some in museums.
