43-6006 was build by North American Aviation at Inglewood CA under contract #AC-30479
issued June 23, 1942 by the United States Army Air Corps. This was the third aircraft in a
block of 100 built under factory serial #NA99-22109. Records indicate this aircraft was
accepted by the AAC at Mines Field (now Los Angeles International) April 3, 1943.

That same day, the aircraft left Los Angeles for Ladd Army Airfield in Alaska. Military
records indicate the aircraft stopped at Long Beach, Hill Field, Gore Field and Edmonton,
Canada among others on its' trip to Alaska.

February 18, 1944 with only 43 hours TT, this aircraft crashed 3 1/2 near Summit, AK in
heavy snow. The pilot, Lt. Edward W. Getter, was killed. The aircraft remained on the
mountain exposed to the weather with only occasional visits by local hunters, some who
inscribed their names and dates onto the engine valve covers.

In the fall of 1977, more than 33 years after the crash, a very determined Waldon Spillers,
with the help of some friends, removed the wreckage from the side of the mountain. It was
too steep even for helicopters. The aircraft remains were shipped to Ohio, where Waldon
rebuilt the aircraft. Working on it almost every day, Polar Bear flew again on July 3, 1985.

In the spring of 1995, with just over 100 flying hours since the rebuild, the aircraft was sold
to Jerry Gabe of Hollister, CA., the current owner.

The aircraft is powered by a twelve cylinder Allison V17110-111 engine and a Curtiss
Electric three-blade propeller. Some modern instruments are installed for safety of flight.
Excess armor plate was removed when not necessary for structural integrity. The real
guns were replaced with light weight replicas. The ammo bays in the wings are now used
for storage. Behind the pilot, a second seat was installed which did not exist in the original
aircraft. The original A model radiator for cooling was replaced with a D model for
improved safety. D model wings were re-skinned at rebuild to look like A type, again for
safety.

The aircraft is painted in 'flat' colors, similar to those used by the Army Air Corps, when the
aircraft was in service with the Cold Weather Test Detachment, Ladd Field Alaska,
1943-1944.

This P51-A aircraft is all American Built. World wide registration records indicate four of
these type still exist. Three, including Polar Bear, are airworthy, one being rebuilt.
However, one or two more are thought to also exist, disassembled.

The Allison engine was built by a division of General Motors. It is the same type as used in
the P38, P40, P63 and some P82's, all American built fighters. Very few were used in the
P51 and only in the A model.

Polar Bear was flown twice in the National Championship Air Races at Reno. She flew in
the Unlimited Bronze Race finishing 2nd in 2005 and 1st in 2006. Dave Morss was the pilot
and Dick Borg, the crew chief.
Rebuild completed in May 1985, from wreck recovered from Alaska. D model wings, oil and
coolant radiators used for safety of flight. Second seat installed.

Licensed Experimental Exhibition. Passenger carrying permitted.

Conditional inspection due 9/01/08.
