Yes, that's it.
Full admiration for your patience
LV means 'LastVagn' (Truck).
At the beginning of the development of heavy trucks, the '6' stood for six cylinders. But that already changed at the beginning of the 1930s, since that time there also have been types with '7' as the first digit. The second digit stood for different series and within the series for different total weights. But there was no direct connection between the numbers and the weights (e.g. 9 not means 9 t). From the mid-1930s, the type designations became three digits. But this did not make them easier to assign.
LF stood for 'LongFrame' and was used for three-axle versions until the 50s.
The AP-truck was converted to a front handlebar. No idea about coachbuilder and year of construction.
Here is your next point.
