previously, between the 1930s and 2004, when new arms were granted or a matriculation of existing arms took note of a barony, the owner was given a "chapeau" or cap of maintenance as part of his armorial achievement on petitioning for the same. this chapeau is described as "gules doubled ermine" for barons in possession of the caput of the barony. an azure chapeau is appropriate for the heirs of ancient baronial families who are no longer owners of the estates. this chapeau was a relatively recent armorial invention of the late lord lyon thomas innes of learney. accordingly, a number of ancient arms of feudal barons do not display the chapeau, and now it is no longer granted.
