This is OO 1:75 - however, the make this iconic mill chimney more usuable on most layouts it has been made 520mm tall - if this was to true scale it would be around 1200mm tall ( this full size version will be available from September ).
 
The base, intermediary colar and chimney top components are all fully premade and coloured. The shaft features Invisiseam, giving depth to the window reveals and a virtally unnoticable join between elevations. 
 
Simple to make.
 
PVA required.
 
Does not include the mill building shown in one photo.
