Britannia (5 Gauge)

Overview
The 5" Britannia is based upon the British Rail Standard Class 7, much as its smaller 3.5 Gauge LBSC designed sister. The 5" Gauge variant was designed by James Perrier with later variants of the drawings amended and marketed by Norman Spink. A sizeable locomotive, it is around 6.5 feet including tender, and is most safely lifted by three people.

Drawings Author confusion
James Perrier finished the original drawings in the early 1970s. Norman Spink redrew them (and unwittingly introduced additional errors) in the early 1980s. The original drawing set was 21 sheets with sheets 15 - 17 covering the tender. Spink's omitted redrawing of the tender as he substituted these with drawings from the Warnett 5" gauge 9F Evening Star model. So Spink's drawings comprise Brit sheets 1-14, 18-21 plus sheets 22-24 from the 9F. When Blackgates took over the Norman Spink business they were confused by the gap in the drawing numbers.
