Eastern National's open top KSWs have formed the basis of floats in Southend Carnival on a number of occasions. In this undated shot, 2380, WNO478, promotes the Cliffs Pavilion's "Summer with the Stars".
2381 had a short career as an open topper, being converted in 1966 but withdrawn at the end of 1971.
See also here and here for shots of it in earlier, closed top, days.
