3 1/2 inch gauge "Britannia"

A well-advanced 3 1/2 inch gauge Britannia, the work of an experienced engineer who had previously built a 5 inch gauge version which is currently in our workshop.

Not the usual LBSC design, but significantly more detailed and closer to prototype - we suspect he scaled down the 5 inch gauge drawings. It includes corrrect valve spindle guides, taper-pinned valve gear, "square drive" return cranks, reverser with acme thread and dummy Wakefield lubricators driven from the expansion link.

Work to date is to a high standard, the chassis turns over very smoothly.
