The King’s Colonials Full Dress and Service Dress tunic breast and cuff buttons were in gilt for Officers and brass for Other Ranks. They are referenced as Ripley Ref No 419 for the cuff button and as Ripley and Darmanin Ref No 140 for the tunic button under KEH. They are of the same design as the second pattern Regimental badge with the Prince of Wales’s plumes over ‘KC’ letters and Regimental motto “REGI ADSUMUS COLONI”. A selection of different size King’s Colonials buttons are shown in Figure 295.
Officer's gilt buttons are noted by Keith Hook as being rimmed and in three sizes with different makers: 25mm QVC wreath, and Firmin and Son; 20mm QVC wreath, and Firmin and Son, and Hobson and Son; and 16mm QVC wreath, and Firmin and Son. He has also noted Other Ranks buttons as a brass un-rimmed 26mm by Hobson and Son, 20mm Hobson and Son, 18mm brass rimmed with a blank back and a 15mm with a blank back.
In my collection I have a single silver sealed back King's Colonial 25mm tunic breast button (See Figure 296a & b) marked Hobson and Sons, Lexington Street, London. Ripley and Darmanin note that there are also white metal King’s Colonials tunic buttons but make no reference to silver buttons. White metal buttons would be consistent with the white metal King’s Colonials shoulder titles noted in Figure 286 which was thought to have been manufactured and worn for ceremonial occasions. I think it is more likely that these were worn by a Senior Officer or the Bandmaster of the King's Colonials. A further note from the Ripley and Darmanin describes a domed button with silver Regimental device on gilt which may have been for an Officer’s cap or Mess Dress. The actual button they describe is shown at the bottom of Figure 295 and it is a three-piece 16mm button with the white metal Prince of Wales’s plumes over ‘KC’ letters and Regimental motto “REGI ADSUMUS COLONI” pinned to the front of the sealed back button made and marked by Firmin & Son.
Hobson and Sons were the makers of the uniforms of the King's Colonials and the buttons bearing their back mark were produced by a sub-contractor probably Firmin & Son as Hobson and Son were not themselves a button manufacturer.
