Recently at the national archives, I was poking around a few huge boxes of unsorted tank and armored car photographs from the 1920’s and 1930’s and made an unexpected discovery. In one of the boxes was a folder with sales photos for various foreign tanks from the late 20’s/early 30’s (Renault NC 27, Fiat 3000 and one or two others), and at the back of the folder was a complete instruction manual (in German) for the Leichttraktor, including a number of photographs of both exterior and interior.
The Swedish army was shopping around for new tanks around 1930, and while they ended up with the Landsverk L-10 and L-30 (strv m/31 and strv fm/31), one of the offers that was considered was for Bofors to license build the Leichttraktor, and that’s most likely the reason why the manual ended up in the Swedish archives.
You can read the manual in PDF form here. At the very end is a few instruction booklets for various sub-parts (fuel distribution system, brakes etc). I’ve only photographed the covers of those; let me know if you desperately need them.
