A small domestic series

The Strv m/31, known to its manufacturer as Landsverk L-10, represented an early Swedish attempt to obtain a modern tracked tank from a domestic factory. Only three were built. Published accounts describe them as a small series used mainly for trials and training, not a mass-produced combat family or a collection of separate prototypes created by every reported equipment change. Sources

Their procurement was linked to the experimental L-30 wheel-track tank, but their identities remains separate. The L-10 was a conventional tracked solution; the L-30 explored convertible running gear. Later Landsverk designs also belong to their own families. A shared company or development background does not justify assigning all subsequent Swedish light tanks to the m/31’s production total. Sources

Procurement and delayed delivery

The account traces Swedish contacts and requirements through the late 1920s and the selection process of 1931. It identifies an October order or contract sequence, but preserves differing dates in the cited material. Those may represent different administrative events; the evidence available here does not establish that explanation conclusively. The protected 1931 sorting year therefore remains a program reference, not a claim that the tanks were already serving then. Sources

Landsverk’s work combined Swedish manufacturing with German design and component connections. Otto Merker appears in the development account, and imported parts later mattered for reliability and spares. This cannot be reduced either to a wholly isolated Swedish invention or to an unsupported claim that the tank was simply a finished German design under another label. Sources

The three L-10s arrived only after substantial delay, with 1935 used as the normal service-entry date in the cited sources. A late-1934 completion reference differ from delivery and acceptance. The vehicles were intended to improve markedly on the older m/21 family, but the long procurement interval and their eventual mechanical difficulties limited the immediate result. Sources

Protection, weapons and crew

The tank used a welded hull with sloping surfaces and a centrally mounted turret. Accounts record protection in an 8–24 mm range, a substantial difference from the more lightly protected L-30 experiment. These values belong to the L-10 reference configuration and cannot be transferred to the convertible vehicle merely because the two were ordered together. Sources

A 37 mm Bofors gun and two machine guns formed the reported armament. The sources use particular gun and machine-gun designations that need to remain visible, including a museum-object description of a 37 mm fm/1932 gun and m/1914-29 machine guns. A conflicting machine-gun designation remains unresolved. Sources

The crew of four worked in a compact hull with the driver forward and the power compartment aft. Observation equipment and provision for communications distinguished the design from older Swedish machinery. The cited accounts do not firmly establish the exact sight models and changing radio installations. Nominal stowage figures of 122 gun rounds and 4,000 machine-gun rounds are retained at the published stated certainty, not presented as newly verified measurements of the surviving vehicle. Sources

Mobility and the cost of sophistication

A Maybach DSO8 V12 petrol engine is identified in the available evidence, usually with a 150 hp rating, while 200 hp appears in another description. Reference values of approximately 11 tonnes and 40 km/h provide a general picture, but combining alternative engine figures with one mass value would create an unjustified precision in derived performance comparisons. Sources

The transmission and suspension were part of a comparatively ambitious design. The source material describes spring arrangements that is distinct from the torsion-bar suspension associated with later Landsverk vehicles. The presence of a later design in the family’s background or legacy discussion is not evidence that its components were already installed on the m/31. Sources

Practical use exposed reliability and maintenance problems. The account connects these to the complexity of the machinery, imported components and limited availability of suitable spares. Those factors help explain why a vehicle with respectable nominal armament and protection did not become the basis of a large immediate procurement. A photograph of soldiers working beside a tank can illustrate the human scale of maintenance, but cannot establish the specific failure or defect without its contemporary caption. Sources

Production and use

Manufacture was concentrated at AB Landsverk in Landskrona. The order comprised three tracked tanks alongside the one convertible experiment. A cited secondary account gives a broader four-vehicle contract budget and a separate allocation for the three L-10s. Sources

Accounts place the Strv m/31’s principal unit service in 1935–1939, while other summaries use 1935–1940 or describe training use into the 1940s. The exact retirement date is therefore less certain than those broad service periods. Sources

A secondary account says the tanks were later used in stationary positions when war began. These details remain unconfirmed in the cited evidence. It is not evidence of another manufacturing batch or proof that the tanks fought. No documented combat record is established in the cited sources, and no export or foreign licensed production of the L-10 itself is identified. Sources

Survival and the documentary record

Strv m/31 illustrates Sweden’s transition from experimental Landsverk designs toward more substantial domestic tank development. Sources

The images cover factory or service-era views, a group of three tanks, a winter scene, and modern museum photographs. Likewise, a modern upload date attached to a historical view is not the date the original photograph was exposed. Sources

The museum record describes a preserved vehicle with its accessories and notes that it has probably been repainted. The dated Axvall photograph provides another useful record of display condition. Neither image alone establishes current museum access or the exact paint and equipment carried throughout the 1930s. Sources
