This is a set of 10 Somerset & Dorset Railway (S&D)/London and South Western Railway (L&SW) cruciform signal post finials for OO Gauge.
Each finial has a peg , atraching it to the sprew, which fits into a 1mm Hole.
This kit is only printable in the FUD & FXD materials and will require cleaning before painting. I recommend washing with warm soapy water then soaking in 'Goo Gone' or a similar non-corrosive product for 24 hours. Then rinsing off with warm water and allowing to dry.
