The first is the Franklin Mint's Junker F-13. This wonderful model comes both as a landplane and a floatplane. The only problem is that it is usually expensive ($50 plus and usually $100 plus) and I can find alot of other cool Pulp stuff to buy for that price.
The other is a Lockheed Orion, another good standard Pulp airplane. made by made by Liberty Classics or Spec Diecast.
