'. . . prototype chassis 13 360, effectively a de-roofed 901 body/chassis, was rolled out of Porsches prototype workshop in early June 1964 to assess its viability. Within a couple of weeks the engineers had made an assortment of mockup top mechanisms for the car, including one that involved a roll bar option/and soft top for inspection by the Porsche heads. According to literature data, a group consisting of Ferry Porsche, F.A. Porsche, Erwin Komeda(head of technical drawings for the 901/911), Hans Beierbach(head of Prototype design)Hans Tomala, Harald Wagner(Head of Porsche sales) and others, all convened around chassis 13360 to review the car.

Following the advice of Komeda , and Beierbach, both of whom argued that it would simply cost too much to stiffen the chassis, change the rear body panels and make other adjustments to accommodate a full convertible, Ferry Porsche decided to approve a roll-bar variation. Even with the decided roll bar option however, it was evident much more work was still required in order to strengthen the chassis satisfactorily. As a result, a few days later chassis 13360 was shipped to Karmann’s workshops to have this done (Karmann engineered all the previous chassis reinforcements for the 356 cabriolets).

The car was subsequently delivered back to the Porsche research department, 2 months later on the 10th of September 1964, and still without a working roof mechanism . The car entered the system with a Cardex that showed the date, its number and its specification as a Type 011/KW, Cabriolet. The roof mechanism and roll bar it was decided, was going to be designed and produced in-house. In the meantime 4 days later, formal production of the 901 coupe begun on September 14th.

Due to the expected start-up and teething problems with the production line of the 901 coupe, and the subsequent attention this required, according to Porsche information it was not until January 1965 that Helmuth Bott(at the time Head of road testing-and who subsequently of course became Professor and head of research and development) was able to take a long evaluation test drive in 13360 to assess its stiffness. In testing the car, according to archive data, Bott found that following Karmann’s work, the car was very similar in stiffness to the 356 Cabriolets. However he did note problems with excess noise and flapping of the soft rear window and top that had been made that required attention.

A couple of weeks later on February 1st 1965, chassis 13 360 appeared on the agenda of a Porsche memo to all of its board members and engineers . It was decided in this memo that the car would have a stainless steel covered roll bar with a Porsche logo, a removable roof panel and a rear soft zipper removable rear window . Shortly after this time the name “Targa” was coined at a sales conference brainstorming session to commemorate Porsche’s wins at the Targa Florio. The Targa design was subsequently registered and patented (No. 1455743) in August 1965 citing designers Gerhard Schroder and Werner Trenkler as its inventors . . .

. . . Chassis 13 360 was acquired from Porsche by German Manfred Freisinger in the mid to late sixties. It appears that 13 360 was likely saved from Porsche’s crusher by Freisinger as the car was acquired without an engine, gearbox ,wheels, tires and front seats. Notwithstanding however, the rest of the car was, and still is, largely in its original and unrestored state, making chassis 13 360 the oldest unrestored Porsche 901/911 in the world! The car features a number of unique features found only on early 901’s as well as of course features that are unique to its status as a prototype cabriolet/targa including plexiglass front vent and side windows!

Being largely unrestored, it also exhibits a number of scrapes, chips and dings on the body, in line with its fascinating history as a test bed. The paint is about 80% original (according to paint depth measurements) yet still possesses a remarkable brightness to the colour despite its 50 years. The speedometer reads about 35k on it. Most trim is very early sandcast so most likely original. Gauges are date stamped to the period. There are also various holes abound in the trim, body, and in other places suggesting attempts at different configurations for roof tops, roll bars, switches, wires, heaters, etc, indicative of the ongoing development role of the car.

Once the car was acquired by Freisinger, he fitted a period drivetrain, front seats, and very early Fuchs wheels and tires. The reason Fuchs wheels were fitted to the car was because the car came with an interesting finding. Although the car was salvaged with no wheels and tires, in the front compartment however there was still a spare tire/wheel in place which it became clear was a very early Fuch and which was unnumbered and therefore likely experimental . Fascinatingly on the side wall of the original early Dunlop tire are the words “Fallversuch” or “test case” scribbled on the sidewall! It is likely therefore that the car was also used as a test bed for the testing of the early Fuch wheels. As a result, Freisinger decided to fit all round Fuchs to the car in keeping with the spare wheel. It is impossible to know which specific engine or drivetrain the car had prior to having its engine removed, as it was quite common practice for the factory to interchange engines/gearboxes etc on Prototypes, according to their test needs and therefore no “matching numbers” concept can ever be applied to prototype vehicles which were never usually sold to the public, unlike regular production vehicles.

Following his acquisition of the car, Freisinger parked the 901 in one of his warehouses where it languished until 2001, amongst his many other Porsches, after which it was acquired by Myron Vernis from Akron Ohio, US, a well-known collector of unusual and rare cars, through a trade/swap deal with a 356 B Carrera. Once Vernis got 13 360 over to the US he re-commissioned the existing motor and car focusing his efforts on preservation, and did not alter the paint or body, wanting to keep the all important body as original as possible. The car was subsequently acquired by the current owner in 2014 and still remains as it was. The car has featured at Pebble beach on the Porsche stand in 2013 for the 50 years of Porsche and is also well known to the Porsche museum in Germany . . .'

[Frank Beck]

I often dream of selling a 911 for ONE MEEEELION DOLLARS without having to do any fix-up before hand.

[Peanut]

Actually Frank, if you look closely, someone moved the wiper arms during the photo soot, so SOME fix up work was apparently done.

Btw, Fuchs, Carpets, Sun visors and on one point also the dash were a later add on, as noted in the description.
