An interesting shot is this. Whilst searching for background data I referred to Bradley's hardback published by wild Swan and found the selfsame picture on pp 57 attributed to Photomatic. With that in mind I shall more or less repeat the short caption: LSWR Adams T1 class 0-4-4T No. 18 at eastleigh in post-1931 Maunsell livery minus the E-prefix. 15" numerals and Urie power classification on the platform valance.
The date on the sleeve staes that this was taken in 1935 which is entirely possible as No. 18 was withdrawn at Eastleigh in April of that year.
