Ndhern sports car, which for a long time was waiting for delivery in the palm next to the museum of code, finally finished the darkMichael Velebny, the renovator’s company. The renewed purchase of the renovation of the preserved frame, chassis, aggregate and the construction of the body according to the original documentation was made using a combination of traditional procedures and the most modern technologies, describes the museum’s spokesman Ondej Lnk.
The Kuptko was created to pay tribute to the 120-year history of the car, which was restored to its original code. The fully operational object is the work of the museum’s code and the prototype character building centre.
Project carkoda 1100 OHCwith internal type designation 968, primarily designed for endurance racing on circuits, was launched in the spring of 1956. At the end of 1957, the construction of the first of two examples with a fibreglass bodywork was completed, which is one of the magnets of the Mladá Boleslav Museum’s collection, explains Lnk. Long-term celebration of the spoches at the wildernesses lining the route of houses and foreign events of historic vehicles. A kind of British importer of code cars. Just for the record: the Mladá Boleslav brand has been active on this important market since 1900.
In the period 1959/1960, the project of 968 pairs of closed designs continued.
And 8,500 boreholes
Unlike the old Koda Sport and Supersport types of the late 1940s, the basis of the water special did not consist of a five-beam chassis forked to accommodate the OHV engine. the Koda 1100 OHC Coup benefited from the lightweight and rigid space frame welded from thin steel tubing. The pedal wheels were guided by an odd-angle pair of triangular arms placed one above the other, with a trailing-arm axle at the rear. Instead of the bundles of leaf springs, the choice fell on the space-saving and light torsion bars, said Ondej Lnk.
Ejecting the engine behind the pedal axle and combining the five stages of the five-axle transmission into a single assembly with the rear axle transmission contributed to such an ideal weight distribution and excellent handling of the dynamic special, he added.
Buy a moving unsealed rod with two bags of shafts in the heads. Hlinka block and crank shaft with the family model koda 440 Spartak, its 40 hp (29,4 kW) and 4 200 rpm bag special with modified combustion chambers and OHC valve train, 9,3:1 compression ratio, two carburetors, dual dynamo-battery Bosch ignition or Scintilla Vertex magnetos and many other modifications of the engine. It achieved an estimated 92 hp (67.7 kW) at 7,700 rpm. This means a specific output of 85 hp per litre of displacement. Short of that, for example, at a pedal speed of 8,500 rpm.
In the vertical at the choice of a tight beam, depending on the nature of the water track, the two-seater with a clay body and an initial weight of only 555 kg reached a maximum of about 200 km/h. Slowing down was taken care of by double-circuit brakes, for the change of the unsprung masses with rear wheel drums at the distributor.
The active driving of the career of the pair of coupes falls into the period 19601962. After its termination, forced by the change of technical specifications and the suppression of the sports car category up to 1,100 cc, the then customary sale of the specials to private buyers followed in 1966. During its use in normal operation, it was destroyed by five crashes.
The first owner of the specimen, whose surviving components were recently used in the reconstruction, replaced the 1 100 OHC power unit with a practical OHV piston from the Felicia model, the engine was then displayed in the Mladá Boleslav recreation centre and it took a full century to return to the car.
The second owner crashed with a heap of bohuel, the boy wreck escaped through a hole in the rear plexiglass, the clay bodywork was irreversibly damaged by the fire. The disassembled rear axle together with the solid axle was then included in the collections of the National Technical Museum in Prague (NTM), which provided it to the Code Museum 25 years ago, first by Lnk. The space frame of the car, which would be broken into four pieces, but the complete pedestrian carriage and other preserved parts were purchased by the Koda Museum in 2014 from a private collector.
Legends Reborn
The ambitious restoration project could not have been carried out without the experience of the Museum’s expert code with the work on the opening. And so without the original technical documentation, preserved in the books of the Auto Code in such a complete form, all the branches and drawings illuminating the construction of the individual groups, Ondej Lnk describes. The original mechanical components showed relatively little wear and tear, and the pattern was only obscured by the deception. The refurbishment of the complete chassis with new cooling, radiator and other elements was completed at the end of 2015.
Instead of the originally considered chassis on display in the museum exposition next to the open one, it was decided to reconstruct it into a fully functional car.
According to the restorers, the clay body of the coupes itself was the most expensive part of the reconstruction. The author of its original design was the internal designer Jaroslav Kindl from Mladá Boleslav. At that time, a detailed mock-up of the chest was created on his basis. The Hlinka panels were hammered out by a group of carpenters, the parts were joined by welds and rivets.
The restoration company connected the hearts with the centre of the prototype building during the reconstruction. After all, the teachers of this specialist once built the buy, delivered to Lnk. On the basis of a scan of 2D drawing in scale 1:1 was created with curves in 3D covered with surfaces. It took hundreds of hours to adjust and correct the shape of the individual elements, for example the pedal and taillight areas. You had to compare the surviving photographs with the drawing documentation and the 3D model. In the virtual studio, the experts could look at the model from all sides and then make further corrections. For a further round shape, models were created in a modified scale and then models of the front and rear corners of the body in 1:1 scale. After the expert assessment, the subsequent corrections and the final approval, the construction of the tailgate, the wheel arches and other elements of the bodywork were completed and hidden from view.
The body of the KODA 1100 OHC Coup consisted of a lightweight and rigid space frame made of thin-walled steel tubes. The pedal wheels were guided by an odd-angle pair of triangular arms, with a trailing-arm axle at the rear.

The body itself was made of 0.8 mm and 1.0 mm thick aluminium sheets, also in the 21st century welded and glued together. The original blue colour of the bodywork, which was created by chemical true anodizing, was used for the purchase. This finish was not hardened in heavy use, and so from the middle of the 1962 season onwards, both cars were given an active red colour.
The codebooks for the reconstruction of the cars included a number of small components identical to those of the contemporary Soviet cars. For example, its two cranks correspond to the Koda 1200 Sedan, which was used by the 440 Spartak and Octavia models, the three-spoke steering wheel covered with black plastic, which is evident in period drawings and photographs, again refers to the early bestseller Popular.
