Russ Saxton says in his excellent book "BR: FROM GREEN TO BLUE", "In the summer of 1966, Toton experimented with a quick-fix repaint into blue. Known as Toton Blue, (it) is the same shade as 'Rail Blue', but the small yellow panels give the illusion of a lighter shade, not helped by the matt finish." The loco's painted thus had no BR emblem, old or new, but maintained the original serif style cabside numbering. The majority appear to have been sent to Toton by Derby Works after Classified Repair without painting, possibly due to Paint Shop workload being heavy at this time.
D47/50/51/55/56/57/58/59/61/64/71/79/91/92/101/105/109/
113/114/116/133/135 were painted in this livery, and D83 almost certainly was, but the loco acquired full yellow ends very quickly, so evidence is required.
Here, D71 The Staffordshire Regiment(Prince of Wales's) is seen at Bristol Temple Meads with the 1N37 9 35am Kingswear - Bradford Forster Square "Devonian", probably early in 1967.
