The 16 toners in the dust rock would have been sheeted over before departure.
Derby Sulzers had more photos of Wirksworth but they have disappeared.
Class 25's were not over common at Wirksworth it was mostly pairs of 20's but I have seen 20, 25, 31, 37, 45 and 47's in the late 70's and early 80's.
