A follow-up to the now out-of-print Siân and Katie - The Twining Sisters, here Stan Buck looks at the looks at the five engines built by Trevor Guest to the designs of Ernest Twining - a small but very influential group as, whilst there has been an explosion of new 15” gauge engines since 1964 when the last Guest/Twining engine appeared, only one has been to ‘standard gauge’ outline, all the others following Twining’s narrow gauge outline ideas exemplified in Katie, Siân and Tracey Jo/Wroxham Broad - but none so elegantly. Lots of background information on the two men, good text and 12 b & w photos, 32 colour photos and 3 drawings. 58 pages. Paperback. SPG
