Panelled coach Winchelsea Beach June 1994

Antique railway carriages converted into holiday homes at Winchelsea Beach - photographed in June 1994
The panelling looks, to me, like that used on South Eastern Railway stock around 1900. Kichenside's 'Railway Carriage Album' has a suitable candidate on page 172. It's the deep panels around the windows, combined with smallish, round-ended panels under the droplights in the doors, that lead me to that conclusion.
