Narrow Gauge Modeller's Handbook Narrow Lines Extra No.4, 7mm Narrow Gauge Association. An introduction to narrow gauge modelling in 7mm:ft, 1/4"/ft and similar scales by Brandon Evans. 20 page booklet with cardboard cover and plastic binding. In overall very good condition however, there is a mark on the front cover - looks like something dripped on it. It's possibly gone through onto the contents page but, if it has, it's not noticeable. Includes "An Introduction to 7mm Narrow Gauge Modelling". An 11 page booklet. Was part of my late father's collection. I will combine postage costs where possible.
