26010 and I go back a long way, back to my 1978 book, and certainly a photo from March 1979. It was new to traffic as D5310 on 6th January 1959, and was withdrawn in December 1992. Earlier preserved on the Northampton & Lamport, it went to the Great Central and SRPS Bo'ness for repairs, then settled at Llangollen in 2009.
Numbered 5310, 26010 approaches Toddington.
Later in the day, approaching Winchcombe...
... where it made a Highland style like meet with 24081.
