Finally pulled out my arty books and got some good pics to show the styles of 105mm howitzer used during the war.
Early style.
Stamped metal wheels,no muzzle break and heavy cradle with square trails and detachable spade anchors.
Limber has the same heavy wheels.
Interim type. Still heavy cradle and trails but muzzle break added and wooden spoked wheels.
Last version. The improved last style muzzle break reduced recoil and enabled a much lighter cradle and tubular trail system to be employed. The same used on the PAK40 but with a larger version of the steel spoked wheels. The last style liber was also way lighter and had large wooden spoked wheels as well… Some were fitted with electric firing devices but those had mixed reactions from the crews as they were not dependable
Hope this sheds some light. Of course, as with all Wehrmacht subjects, there were combos of all these elements as well but these were the most often seen/used types.
