There are not too many references on the Sd.kfz.11 but I found a few....there is a new Nuts and Bolts coming out on this vehicle in February but I cannot wait, never been a patient man!
First, the Militaria book, quite good to be honest, lots of colour plates and pics of this vehicle and its variants in different theatres...
Then the Ground Power, whenever I start a new vehicle I always round up the Ground Powers relevant to it, they have great pictures and scale plans....
Lastly an Allied Axis with some good shots although not too many
