I'm in the process of converting a Panzer III into a bergepanzer III which obviously is not too disimilar and its been a hoot. The only real problem I'm finding are things like joints and pullies for the crane to work etc. however I did find some stuff at (of all places) www.cornwallmodelboats.co.uk which should sufice till I can work out something better. If I can pluck up the courage I will post some photo's once its completed.
