This is a set of 20 OO/HO scale chimney tops as used on the Somerset & Dorset’s terminus station at Bournemouth West. These iconic fins made the building stand out and are an essential part of any model of the station.
These parts are designed to be printed the Smooth Fine Detail Plastic materials and they will require cleaning before painting. I recommend washing with warm soapy water then soaking in 'Goo Gone' or a similar product for about 24 hours. Then rinsing off with warm water and allowing to dry.
