D2 Bias side of a bowl: the side of the bowl that is the more rounded of the two sides, which is identified by the small grooved rings surrounding its centre.
52.1.3 Each set of bowls can carry a player’s individual emblem, logo or engraving as a distinguishing mark on both sides of every bowl.
- 18.104.22.168 The distinguishing marks must be the same design and colour but can be different in
- 22.214.171.124 The distinguishing mark on the bias side of the bowl must be inside the smallest grooved ring surrounding its centre.
- 126.96.36.199 If there are grooved rings surrounding the centre of the non-bias side, the distinguishing mark must be inside the smallest ring.
- 188.8.131.52 If there are no grooved rings surrounding the centre of the non-bias side, the distinguishing mark must be inside the indentations designed to help the player grip the bowl during delivery.
- 184.108.40.206 As well as the distinguishing marks, each set of bowls can carry a player’s name or signature. Imprints on the running surfaces of bowls must be avoided
220.127.116.11 All bowls belonging to players within a team or side must have these markings on them and the markings must all be the same design and colour. However, players may use markings which are different in size from those used by other players in their team or side where this is necessary due to differences in the sizes of either the manufacturers’ rings or distinguishing marks on the bowls. (This section refers to the provision of adhesive labels to identify a team's bowls at some competitions, not the engraved markings on either side of the bowl.)
53.1 Licensed Manufacturers and Licensed Testers are entitled to imprint the registered World Bowls Stamp on the bias side of bowls. Imprints on the running surfaces of bowls must be avoided wherever possible.
