WW2 German Limbers (GR36)

[hamsterking]

I have recently bought a number of GR36. The body of the Limbers are in a very distinctive step shape. While not doubting the quality of the sculptors research I'm most curious about the appearance of the limbers and was looking for some source photos. But a quick check through my library and on the Web hasn't  revealed any relevant picture sources. Can anyone point me at some relevant pictorial material?
