Pan Am Models
I have a large collection of model aircraft. They vary in size from several inches to several feet. Though the larger models are majestic in the last few years manufacturers Gemini Jets, Dragon Wings and Aero Classics have produced high quality miniature models. Most of the current miniature models are of the 1/400 or 1/500 scale. Beautiful as these miniature models are none of them were produced during the Pan Am era.  Below are a few samples from my collection.
The scale model below shows a Boeing 314 (NC 18605 Dixie Clipper).  The fuselage measures 18 inches with a wingspan of 25 inches.  This aircraft was in service with Pan Am from 1939 to 1946.
The scale model below features the Boeing 377 "Stratocruiser," (N1040V Clipper Invincible).  The Stratocruiser was queen of the Pan Am fleet from 1949 until the introduction of the Boeing 707 jet in 1958.  The Stratocruiser was mostly configured for all first class service and seated approximately 60 passengers.  This model is 18 1/2 inches long with a wingspan of 23 1/2 inches.
Below is a scale model of a Lockheed L1011-100 aircraft.  Pan Am never flew this type.  Most likely this model was created by Lockheed in the late 1960s when they were trying to convince Pan Am to buy the aircraft.  The model measures 21 inches with a wingspan of 19 inches.  In the late 1970s Pan Am would place an order for 12 of the smaller long range Lockheed L1011-500.  This version of the aircraft would fly with Pan Am from 1980 to 1986 with different livery markings on the fuselage..
The Virtual Pan Am Museum
A collection of Pan American flying boat models from largest to smallest.
A large model of Pan American's Boeing 314 tail number N18605 the Dixie Clipper.
On top the model on the left is a Pan American Boeing 307 Sratoliner.  On the top right is a Pan American Douglass DC3.  Both of these models were produced by Atlantic Models in Florida.  Below left is the Ford Trimotor and on the right another example of the DC3.  The smaller DC 3 was produced by the famous English toy car manufacturer Corgi.
On the left are three examples of the Lockheed Constellation.  On the right two examples of the Boeing Stratocruiser.
The Douglas corner with high quality representations of DC3s, DC6s & DC7s.  The Yellow and green aircraft on the right is from sister company Panagra.
Boeing 747s from all different liveries, sizes and  manufacturers.
Boeing 707s & Douglas DC8s of all sizes and manufacturers.
Boeing 727s of all sizes and manufacturers.
Herpa Wings 1:200 scale model of Pan Am  747 tail number N755PA Clipper Sovereign of the Seas.
Dragon Wings 1:400 scale model of Pan Am's first 747 tail number N747PA Clipper Young America.
In the mid 1950s as Pan Am designed a new livery for jets a white globe on a blue tail was tested on several piston aircraft but never adopted for jets.  This model shows that design.
Pan Am Boeing 707 tail number N884PA Clipper Nightingale produced by Gemini Jets in 1:400 scale.
Through the years various manufacturers produced toy models for children.  Seen here are a combination of Boeing 747models and one DC 8.
With the exception of the helicopter the flew customers from the 59th Street Heliport to JFK airport none of the other models in this photo ever flew for Pan Am.  The futuristic space craft was featured in the film 2001 A Space Odyssey.  Additionally, Pan Am never flew either the Concorde or the MD 11 seen in the lower left of the photo.

In the last ten years small high quality models have become very popular for collectors.  These model are a combination of metal & plastic.  Most of these models are 1/400 or 1/500 scale.  There are three principle manufacturers Gemini Jets, Dragon Wings and Herpa.  The below models (not on stands) are examples of these high quality "mini" models.  There are additional examples of this type of model further down the page in the thumbnail / slide show area.
Fantasy Planes
Through the years some model producers have produced planes that either never flew for Pan Am or never flew in a particular livery.  Below are several sets of examples.

On the left is the Boeing 707 that left the Pan Am fleet in 1980.  The "Billboard" livery didn't appear until 1984 and was never used on the 707 fleet.  On the right is a Boeing B-52 bomber.  Pan Am never had any bombers in the fleet!
Slide Show
Below are 3 examples of 747 liveries that were never flown by Pan Am.  These designs were simply created by the model manufacturers.  In addition the 747 in the upper right and bottom left are 747-400s a version of the 747 never flown by Pan Am.
Of the 4 aircraft below only the Lockheed L1011-500 (upper left) was flown by Pan Am.  However, it was leaving the fleet when the "Billboard" livery was adopted and none were ever repainted in this style.  The Boeing 777 (upper right) made its first commercial flight 5 years after Pan Am shut down.  The Airbus A380 (lower left) came into being many years after the demise of Pan Am.  The Concorde (lower right) was initially ordered by Pan Am in the late 1960s.  However, the order was canceled prior to any aircraft being delivered to the company.
Finally, a clay model of a Pan Am Airbus A310 created by Pan Am fan James Page in his high school art class.
In the 1970s a Japanese company produced a Pan Am 747 model that came with miniature ground equipment.  The ground equipment includes a fuel truck, luggage conveyer belt, cargo tug & cart, an aircraft tug and a passenger bus all pictured to the right.

In the 1960s Pan Am offered helicopter service from the roof of the Pan Am Building in Manhattan to JFK airport.  The battery operated toy helicopter below is a representation of the Boeing helicopter that operated the service for Pan Am.
