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.
For some unfathomable reason I can access the original Blog but am excluded from the current Dorset Railway Modelling of which there are 800 odd posts.
I will try and get to the bottom of this- not very hopeful though!
