GWR Milk Van type O4 : This kit represents the most numerous type of six wheeled GWR siphon, designated O4. There were a number of types and variants of the GWR milk van. This vehicle type had three double doors whereas earlier vans had two double doors. An entire book was written on the development of these vehicles. (“Great Western Siphons” by Jack N. Slinn, Pendragon books 1986 in association with the Historical Model Railway Society).

This kit features:

• An unusual and interesting prototype
• 3D printed roof
• 3D printed solebars and brakes
• Buffers included
• Our wheels D3D-01 (3 axles wheels + mansell inserts) are compatible with this kit

A difficult and tedious task encountered when modelling pre-grouping rolling stock is the preparation, cutting out and alignment of the framing.

Build impressive rolling stock using this kit as the basis of your next project.
