This crest has been in use since George Dunbar (1340-1422) Earl of March and Dunbar, Lord Annandale and Man, whose crest was a bridled horse’s neck and head. This was used to seal documents dated to 1371 and 1373, making this one of the oldest crests still in use today, although his horse emerged from a coronet, rather than a simple wreath as it does now. Prior to this, the medieval seals used by the earls of Dunbar featured a man in armour upon horseback. (Nisbet’s System of Heraldry,1722, p.268; R.R. Stoddart, Scottish Arms being a Collection of Armorial Bearings 1370-1678, p.10).
The motto ‘in promptu’ (meaning ‘in readiness’) is much more modern, and not recorded by Nisbet in 1722 (although it is mentioned in relation to Trotter, whose crest is a man holding a horse). The earliest instance of this seems to come in 1798, when it was recorded as the motto of Dunbar of Mochrum (Sir Robert Douglas, the Baronage of Scotland, 1798, p.113-8). The Dunbars of Mochrum are the currently chiefly family of the Dunbars, as the earls of Dunbar were forfeited to the Crown by King James I, and the last earl died in 1455.
