The Lyons Museum included a few larger types in the hangar.  At one end they had both a DC-3 and a C-47.  While notionally different types, they are in principle the same aircraft and one that Douglas churned out in huge numbers.  The DC-3 was configured in a slightly more comfortable way than the C-47 though.  Troop transport was not a luxury business.  Get as many people and bits to where you are going as you can.  The paying passengers were a more demanding crowd and the interior is designed to make them feel like they were being treated accordingly.  Either way, they are both great looking aircraft.
