Class Details by Steve Llanso of Sweat House Media

Class Dee (Locobase 10496)

Data from "Locomotives of the Wrexham, Mold & Connah's Quay Ry," The Locomotive Magazine, Vol XI (15 March 1905), p. 41.. Hudswell works number was 119

Although the Duke, shown here, and the Dee, shown in Locobase 10497, shared the same boiler and grate, the earlier locomotive had taller drivers and a bit more coal bunker space.
