The original 904 Carrera GTS with chassis number 904-31 was originally ordered and planed to be constructed for a Porsche client named "Brockhaus" via the Porsche official concessionaire; Baden-Auto of Freiburg, Germany.

This car was completed on February 27th, 1964 as a standard client-racing 904 (1st series) in normal racing configuration. The car was completed as a "domestic" use Racing" vehicle and issued Freiburg, German Road-registration "FR-CY 111"

The car was not sold or delivered to "Brockhaus" but instead recorded as being sold new to Dr. Joseph Ruby on February 27th, 1964. The car was officially delivered through Baden-Auto to Dr. Ruby.

Porsche retains completion records for 109 different examples of the type 904. With chassis numbers logically ranging from 904-001 through 904-108. (Additional bodies and chassis with higher chassis numbers were completed but used solely in the repair of earlier cars do to road accident and racing attrition.)

Production took place from approximately December 1963 running until June of 1966. The production of the 108 examples was far from linear with some early chassis numbers not being completed until much later and vise-versa. The production records for each chassis usually identify the original owner, engine and gearbox number as well as the selling date, color of the car and selling destination. Several examples also record Factory authorized repairs or subsequent work.

Previous to his purchase of the 904, Dr. Ruby had been involved in with a variety of different racecars in various continental events. He had some very well publicized successes with a DKW which brought him to the attention of the Porsche Factory. Eager to see the 904s in competition with favored client's, Dr. Ruby's order for a new example was given priority and the 904 originally planned for "Brockhaus" was instead invoiced to him.

The first recorded race entered by Ruby was on May 31st, 1964 at the 1000kms of Nuburgring. Ruby entered the car for himself under his own name as well as his friend and fellow German co-driver, Sepp Gregor.

The two were assigned race number 64. Dr. Ruby was driving the Porsche in the official practice session when he had a very hard accident that totally destroyed his original car. Fortunately, Dr. Ruby escaped without injury.

The race itself was however an overwhelming success for Porsche's 904 with no fewer than 8 different cars finishing in the top 15!

Immediately after the Nurburgring race, a brand new replacement 904 (chassis 904.1.116) at the end of the production line was given Dr. Ruby's original chassis number (904-31) and the new car invoiced and delivered to him by Porsche in June of 1964. The official record of this is recorded on page nine of the "FR-CY 111" Wagon Pass log book remarks section for this car. This entry was recorded on September 30th, 1966 and it states the following:

Das Fahrzeug erhielt einen Ersatzrahmen, an dem die Fahrgestell-NR 904031 angebracht wurde. Die im Ersatzrahmen bereits vorhandene Nr. _____ wurde durchkreuzt. Firmenbescheinigung über die Herkunft bzw. den Austausch des Rahmens wurde vorgelegt. Freiburg/BR. 30, Sep. 1966 Dipi.-Ing. Blum-Neff

The vehicle received a spare framework, at which the chassis NR 904031 was attached. The No. already existing within the spare framework was through-crossed. Firm certificate over the origin and/or. the exchange of the framework one submitted. Freiburg/Bremen September 30th, 1966 Dipi. Ing. Blum Neff

A close examination of Dr. Ruby's 904 Porsche clearly shows the two chassis numbers with the "904.1.116" clearly crossed out. (See accompanying photographs)

Several sources over the years have stated that Dr. Ruby's original 904 (904-31) was simply rebuilt by the Porsche Factory with a new body. This is not the case and both the Porsche records, photographic evidence and original documents clear that the his original 904 was completely destroyed.

His second 904 was an all new car completely different than his first example. The new car simply used his old chassis number in order to save tax and road registration expenses. As already noted this is carefully recorded both by Porsche in their records and on the original German Wagon Pass.

This new 904 was very different the Dr. Ruby's original 904. His replacement 904 was an extremely late specification example with many revisions that had been learned and incorporated into the initial design.
Most notably Dr. Ruby's new 904 was a "high-specification" endurance or "Le Mans Specification" race version, one of five known to have been completed.

Dr. Ruby's new 904 included a supplemental gas-heater, 110-liter, center-fill fuel tank, twin, throttle cables, FIA rally exhaust system, revised and reinforced frame and body-work, and the by-pass, high RPM supplemental oiling system specific to the endurance (Le Mans) cars. Like his original 904, his new 904 was finished in the standard metallic silver finish with blue-cloth seat interior. No other options or features were recorded at the time of completion.

One year later on May 8th, Ruby entered his new 904 in the National GT race at the Nurburgring. The field of cars was dominated by more than a dozen different 904s and their various driver/entrant pairings. Ruby ran his best recorded race here finishing a well earned 5th overall and 1st in class.

On May 23rd, 1965, Ruby again entered the car in the 1000kms of Nurburgring. This time he was assigned race number 76. As in his previous attempt a year earlier his luck did not hold out. Pre-race mechanical problems in practice forced him to withdraw before the race started.

The car was then raced by Ruby in the August 28th/29th, 1965 running of the "Marathon de La Route at Spa. The car however did not finish as a result of electrical problems. (Original scrutineering sticker and entry sticker from this race are still on car to this day)

For the 1966 Season, Dr. Ruby and his Co-driver, Schwartz, scored an impressive 1st in class in the grueling two day Rallye Waldkirch open road race. The race was run on October 8th and 9th with Dr. Ruby's 904 being the sole 904 to finish.

This was to be Ruby's last recorded race with the car. From that point Ruby used the car solely on the road being last registered on August 11th, 1977. From that time to time until his death in 1979, the car was in storage. Dr. Ruby's 904 was then given by his widow for display purposes to the prestigious Sinsheim Ausgestellt Technik Museum where it remained on display until January of 1990.

While at the museum, the car remained little used except for a Porsche Parade and Tour Event held by the museum in 1986. For that event, the car was temporarily registered again for the road on April 30th, 1986. After the event the car went back on public display in the Museum.

In the Spring of 1990, Dr. Ruby's wife, agreed to the sale of this car after being contacted by the well known 904 expert, Mr. Heinz M. Heinrich. Heinrich and the Danish Car Dealership, Inner Circle arranged for and completed on April 22nd, 1990 the sale of the car to the world famous Yokota Museum Collection in Shikoku, Japan. The selling price without commissions was $775,000 and the car was formally invoiced for DM 1,050,000 on April 22nd 1990.

The car was flown from Hamburg, Germany to Osaka, Japan two days later on April 24, 1990. The original shipping documents, air-way bill and invoice all record the car's chassis (904-031) and engine number (99018.)

Until our recent purchase this car has remained on display at Mr. Yokota's museum for the past 17 years.

Today, this car has covered just 44,549 kilometers (27,681 miles) from new! This is a completely matching number car, front-to-back! It retains all of its original paint as well as being still fitted with its original engine and gearbox, windshield, side and rear plexi windows etc... The spare tire and wheel are the original delivered new with the car. The wheels and tires currently fitted were installed by Ruby in 1969 and have never been replaced. This car is the sole known example that still retains its original supplemental gas-heater as well as the full "Le Mans" factory high-speed oiling engine kit etc…

The "time-warp" original appearance of this car is impossible to describe. It has its original ultra rare, factory air box / filters and the original homologated rally exhaust system. As previously noted, while still holding air and a sight to behold, the car is currently sitting on the same set of tires last fitted in 1969!

This single owner from new 904 Porsche is universally considered by most experts to be the most original, correct and un-molested 904s left in existence. As such this legendary car is without equal of any kind and the one by which all others will be judged for authenticity and originality.
