In this blog we have a NSWGR bogie sheep wagon built from Casula Hobbies GSV wagon parts. You can buy all the kit parts you need to build the wagon from Casula. The kits are a simple kit bash. It would make a great starting point for those who may wish to go one step up from just kit building and get into kit bashing and scratch building.
The weather techniques are the same style as used in the BCW blog posting earlier.
