At the new Swedish MV Museum, Arsenalen there is an FWD from 1917 that has been hidden in a "secret" storage for years - original (not restored). There is also an LK II from 1918 with original Benz engine, and as I understand there is another LK (upgraded with Scania engine) that will be restored into running condition.
The Renault NC 27 is a "postwar" vehicle, but as far as I know the only remaining in the world.
The "Pavesi" is not a Pavesi, but a Swedish built NOHAB Artillery Tractor from 1928.
