LMSR Stanier designed pull-push fitted from new 0-4-4T no. 6401 in 1938 according to the sleeve note but I have my doubts about that unless it's been burnished for an exhibition of course. I think this was taken at Derby when the loco was new in December 1932. 6401 became 1901 circa 1947 and then 41901 under BR ownership. Withdrawal came at 1C watford mpd in November 1959.
