1:100 scale Norwegian Leopard 1


The Leopard (or Leopard 1) is a main battle tank designed and produced in West Germany that first entered service in 1965. Developed in an era when HEAT warheads were thought to make conventional heavy armour of limited value, the Leopard focused on firepower in the form of the German-built version of the British L7 105-mm gun, and improved cross-country performance that was unmatched by other designs of the era.

The Leopard quickly became a standard of European forces, and eventually served as the main battle tank in over a dozen countries worldwide. Since 1990, the Leopard 1 has gradually been relegated to secondary roles in most armies. In the German Army, the Leopard 1 MBTs were phased out in 2003, while Leopard 1 derived vehicles are still widely used. The Leopard 2 MBTs have taken over the MBT role. Leopard hulls have been re-used in a wide variety of roles.

Mystery NATO tank almost done


Mystery NATO tank almost done! Only minor tweaks to hatches are needed.

From Fjodin's archives - 1:100 Vezdekhod Tank


Want to present an unfinished model of tiny Vezdekhod tank from my archives. I will finish it right after Mystery Tank.

The Vezdekhod (Russian: Вездеход) was the first true tank to be developed by Imperial Russia during World War 1. The word Vezdekhod means: "He who goes anywhere" or "all-terrain vehicle". It did not however progress further than a pre-production model, due to problems in the design.

In August 1914, a 23-year old aircraft designer Aleksandr Porokhovschikov offered to build a vehicle with cross-country capability. The working drawings and estimate were finished by January 1915, and on January 13 approval was given to proceed with construction, the project being supervised by Colonel Poklevskij-Kozello.

The Vezdekhod had a welded frame which ran on a wide single track made from rubberized fabric stretched over four drums, with a fifth drum tensioning the track from above. Two small wheels were placed on the sides of the track, and could be lowered to steer it, being controlled by a steering wheel. The machine was propelled by a 10 hp petrol engine driving through the rear drum. Porokhovščikov intended that the Vezdekhod should run on the back drum and its wheels while on firm ground, while on soft ground it would lie down on its track. Preliminary automotive testing began on 18 March.

Construction of the prototype began in February 1915 with the first tests on a paved road being carried out in May, with further tests proceeding until the end of the year. In cross-country trials the Vezdekhod was reported to be capable of a speed of 40 Verst per hour (26.5 mph) with simulated armor weight but proved impossible to steer using the wheels provided for that purpose and the project was therefore rejected, the Military Technical Department forbidding further work on it after December 1915.

The actual performance of Vezdekhod is debated, but according to the test commission Report No. 4563: "It appears that Vezdekhod is a sound and practical idea; it can achieve a speed of 25 Verst/hour (16.57 mph). In addition, Vezdekhod can ascend a slope of 40 degrees inclination, cross a trench three metres wide, and a vertical obstacle of 3/4 metre. All significant holes and rough surfaces were crossed wherever tests were carried out. Vezdekhod steers easily during fast motion, and turns very satisfactorily. In all, Vezdekhod crosses terrain and obstacles impassable to conventional motor vehicles."

The project was reopened in October 1916 but no further progress was made.


The original blueprints, and possible photographs have been lost to history, perhaps due to the Revolution of 1917. After Russian newspapers published news about the first British Tanks in World War I, Porokhovščikov argued that the Vezdekhod was the rightful first tank. After the Revolution, Soviet propaganda promoted the idea that Vezdekhod was the first tank.

From Fjodin's archives - 1:100 Rybinsk Tank


Rybinsk tank It's the project of a medium tank developed in the Russian Empire in 1915-1917. One of the most mysterious armored projects created in Russia during the First World War - the information about it is very limited and sketchy. According to the most common version, the tank was created using a Holt tractor. There is also reason to believe that the the basis of a Rybinsk tank design was a not adopted project of french Colonel Etienne in 1915.


The initial draft of a tank was proposed to the military department at the end of 1916, but the events of 1917 put an end to further work in this direction.

The tank have unusual layout. It have driver and machine gunner at front of a vehicle but 75mm naval gun at REAR of a vehicle. Tank was intended to be used as infantry support vehicle. Tanks should move at front of advancing infantry lines and use their machine guns to fight the enemy infantry. If they encounter enemy fortifications, tanks should steer and use their rear guns.


Rybinsk Tank specifications:
Size: 5 meters long, 2 meter tall and wide
Crew: 4
Armor: 12mm front, 10mm rest
Maximum speed: 10-15 km/h on plans but 8 km/h are more realistic because tank have Holt tracks and same weight like French Schneider CA1 tank
Armament: 75mm 1892 canet naval gun
                     Maxim Machine Gun

1:100 Mendeleev revamped


Two days ago I decided to add some details to Mendeleev Tank. Note that exaggerated ladder piece will be 1 mm thick after printing.

Here are updated tank specs:

Crew: 8
Maximum speed: 10-15 km/h on plans but 3-5 km/h according to modern research
Armor: 150mm front, 100mm sides and rear, 76mm roof
Armament: 120mm 1892 Canet naval gun
                      Maxim Machine Gun

LKII and Ford 3-Ton M1918


Here are two other obscure WW1 vehicles that I made year ago.

NOTE that these models are 85 % finished and still need final touches and additional details on tracks and hull.

I am going to finish them after Norwegian NM-142 and Mystery Nato Tank that almost done.

LK-II is a German WW1 tank. Only two prototypes were produced by June 1918, and were followed by orders for 580 tanks, which were never completed. Tank that was later used by Sweden up to 1938.

The Ford 3-Ton M1918 was one of the first light tank designs by the U.S. It was a small two-man, one-gun tank. It was armed with a M1919 Browning machine gun and could reach a maximum speed of 8mph. The 3-Ton had a 17 gallon tank that gave it a maximum range of 34 miles. A contract for 15,000 of these vehicles was awarded; however, the U.S tank corps felt it did not meet the requirements they wanted. The contract for the 15,000 tanks was ended by the Armistice, leaving only the fifteen original vehicles produced.
