 It was re-boilered around 1880 with what was then a typical contemporary design, a round-topped boiler with raised firebox.When restored for historical display at the L&MR centenary of 1930, this was then hidden beneath a purely decorative brass facsimile of the original haycock boiler.This simplified round-topped firebox within an external brass pyramid was reproduced in LBSC's 1953 5" gauge model engineering design "Titfield Thunderbolt".
