I have only painted one side of the compartment sides to aid Meking the whole lot together.Otherwise it means scraping off the paint where you want something to stick.
I am the Dorset Area Group Organiser for the 3mm Society. The reason for choosing 3mm is that I can do some real modelling without the distraction of Ready to run models. At present I have a 3mm layout, Hennock, which has been exhibited several times. It is also booked for several shows in the future. Currently I am building another 3mm Layout-Teignford. Please mail me if you have a similar interest,query or wish to convert to 3mm.
