This was a WWII four engined bird that started life as a twin. It served with many countries, though not always in WWII, including Poland, New Zealand, India, Egypt, Pakistan, and Canada. The initial four engined model had a very severe flight stability problem. It was used for everything from glider tug, maritime recon, to multiple types of transport, including civilian, paratroop, aircraft fuselage, and even Maharajah.
