1970s. Later it was revived in the 1980s in LMS Crimson livery, and was subsequently released in a limited-edition pack in its
Caledonian colors. In 2007, the locomotive was released in LMS Black livery, with DCC capability being added to allow the locomotive to fit the then current range. A train pack entitled 'The Last Single Wheeler' was introduced in 2010 featuring the locomotive in LMS Crimson livery again, with three LMS carriages of the time. London Road Models supply an etched kit for a 4mm model, which creates a model of 123 in its pre 1924 condition, when it was re-boilered by the LMS.
