A small experimental family

The Landsverk L-100 and L-120 were small Swedish light-tank projects whose history is much larger in the literature than the number of vehicles actually built. The account groups them as a related development program, while retaining separate identities for the L-100, the less firmly documented L-101 proposal, the L-120 and the Norwegian vehicle usually called Rikstanken. Sources

These were not the foundation of a large production fleet. Trials, export interest, a complete tank and unarmored chassis recur in the accounts, sometimes without a clear distinction between them. The family therefore requires cautious production language. Norwegian local completion of an L-120-based vehicle differs from Swedish manufacture of a fully equipped export tank. Sources

Industrial setting and early proposals

Landsverk's interwar work combined Swedish industrial ambition with opportunities to supply small armies and explore new armored-vehicle ideas. Accounts associate the projects with the Landskrona design environment and Otto Merker, but notes that detailed primary documentation is sparse. Broad statements about German influence do not identify the origin of every component or establish a direct lineage to every later Swedish tank. Sources

The L-100 is placed around 1933–1934 in the development narrative. Published images and secondary accounts do not consistently agree on dating or armament. A 20 mm gun sometimes attributed to the L-100 may instead be entangled with the L-101 proposal. Published accounts describe that problem rather than assigning a machine gun and a cannon to successive production models without evidence. Sources

The L-120 followed Swedish interest in a very light vehicle and is associated with requirements in 1936 and trials in 1937. The program did not become a regular Swedish tank fleet. Export interest also needs to be kept separate from completed deliveries; the Norwegian acquisition is the principal concrete foreign connection described in the cited sources. Sources

Layout, protection and weapons

The general arrangement was a compact two-man vehicle with a small turret and light armor. Sources

The L-120 and Norwegian vehicle require their own published figures. Local construction altered what was actually carried and protected. The Norwegian turret and iron body is not established as equivalent to a documented Swedish armor scheme simply because the chassis came from Landsverk. Sources

Machine-gun and 20 mm references are particularly easy to merge incorrectly across the names. Ammunition capacity and exact mounting arrangements remain poorly established. A line drawing or photograph can help identify visible equipment, but does not fill undocumented details of ammunition stowage, sights or protection. Sources

Published Landsverk L-100/L-120 weights commonly fall around 4.5–4.8 tonnes, with differences between configurations and measurement conventions. Sources

Running gear and performance

Accounts describe torsion-bar suspension in the development account, but does not support an unqualified worldwide priority claim. The cited accounts do not firmly establish suspension type, wheel layout and prototype identity. Sources

Engine and transmission information is inconsistent. The Norwegian reference is commonly an approximately 85 hp Volvo engine, while speed claims range from roughly 25 to 50 km/h in differing accounts. Those figures may describe different conditions or states, but the material does not demonstrate a single explanation. They therefore remain qualified rather than being reconciled by inventing an operational cause. Sources

Brake problems and difficulties with the locally completed vehicle appear in the service narrative. Such reports belong to the specific test or operating history, not automatically to every L-100 and L-120 proposal. Radio installation, fuel capacity and ammunition stowage remain unresolved questions. Published figures preserve unknowns instead of borrowing values from the much better documented L-60 family. Sources

Swedish testing and Norwegian completion

Swedish evaluation and Norwegian use were different stages with different institutional purposes. Sweden investigated the concept but did not adopt it as a standard tank. Norway acquired a chassis and completed a vehicle locally, using it for training and experimentation rather than establishing a substantial armored formation. Sources

The Norwegian names Rikstanken, Kongstanken and Norgestanken belong to the vehicle's local story, not to a series of separate Landsverk designs. Published accounts describe a practical late-1930s service window but retains disagreement over exact receipt and completion dates. Chassis delivery, completion of local bodywork and entry into training remains separate events. Sources

Accounts describe the vehicle with Norwegian cavalry formations and place its final military episode in the German invasion of April 1940. The available evidence does not establish successful combat employment. Its abandonment or capture is not evidence that it entered a sustained German operational role afterward. A photograph of captors posing with it would establish possession and a scene, not a complete subsequent service history. Sources

How many vehicles existed?

Production descriptions range from one complete tank plus one or two chassis to at least three L-120 prototypes. These totals may count different stages of assembly, but the cited factory and acceptance information does not settle the distinction. Sources

L-100 and L-101 records add another boundary problem: a proposal, an incomplete project and a tested tank cannot all be counted as completed combat vehicles. The Norwegian conversion reused an imported chassis rather than constituting an unrelated Swedish-built tank. Sources

The correct next step is a register of individual physical objects supported by order, delivery, workshop and trial records. Until that exists, Published accounts describe the published limited-production language and retains the alternatives in its tables. This is more useful than treating every designation in a broad family heading as proof of another tank manufactured. Sources

Significance and evidence limits

The projects illustrate the gap between an ambitious light-vehicle concept and the practical needs of an army. Sweden's experimentation and Norway's very small training effort produced different experiences from the same broad technical environment. The Norwegian vehicle became symbolically prominent, but one experimental machine did not constitute a credible armored force. Sources

The L-100/L-120 history is not established as the direct origin of every later Swedish light tank. The account itself distinguishes the more consequential L-60 line. Connections to later specialized projects remain leads requiring precise drawings and construction histories, not completed lineage decisions. Sources

Preservation claims also remains uncertain. The images are historical reproductions rather than a photographic survey of an established surviving tank. The cited accounts do not firmly establish their dates and provenance. The unresolved questions are substantial enough that a visually convincing illustration could easily conceal more uncertainty than it explains. Sources
