Very nice collection indeed! The Air France looks like a French "Joustra"-model - all the other Connies seem to be from "Arnold" in Germany. Does your Lufthansa-Connie have the tip-tanks?
Here are two other Lufthansa-Connies from my collection made by "Tipp&Co" from Germany. One with a friction-mechanism, the other is battery-operated. I love the nose gear on the electric-powered model!
