LNWR George the Fifth 4-4-0 No 25373 Ptarmigan in the late 1930s.
Renumbered to 25373 in May 1936 this loco became the last 'George the Fifth' (along with 25350) not being withdrawn until 5/48. Since 1936 it has acquired driving wheels with smaller bosses but never received a Belpaire firebox. It was allocated BR no. 58012 but never carried it before withdrawal
