One of my favorite aspects of the game is the incredible variety of skins (and the sheer quantity of them - over 7,000!). I've been scanning through the files in order to create a list of my favorites. While doing so I ran across a couple of old Pfalz models that I don't ever remember seeing during a campaign flight.
The two-seater (AI) has the only skin files that I've seen that are identified as being for 1914.
The single seat model is the EIII.
