Inlaid a€?Ca€?
a€?Ca€? was first inlaid in side of the mouthpiece around 1919. This was a complicated inlay requiring three drillings. Initial, a spherical white inlay had been placed, then heart with the white is drilled down, and a smaller round black inlay was actually put. Finally, another boring was developed to get rid of the open part of the a€?C,a€? and an even small black inlay is inserted. This inlaid a€?C,a€? referred to as a€?three-piece C,a€? got persisted till the Cadogan age into the 1980s. However, the a€?Ca€? inside the 1920s and early 30s is much thinner and much more delicate versus one post-war. Cadogan 1st changed the a€?Ca€? to an individual drilling with an inlay that had the a€?Ca€? in the centre, and a lot more recently they turned into a laser imprint.
