Flush Glazing for older models

Many older coaches, especially Hornby Mk2 and older Graham Farish coaches - and locomotives (e.g. Hornby Dublo diesel locos, Triang DMUs) use acetate sheets behind fairly thick mouldings for windows, which do not look particularly prototypical.

These pages cover my efforts at making 3D printed windows using ultra-clear resin to simulate flush glazing on a budget.
