Got this insert and it is supposedly from a 5513. What is weird tho, is that it has a glass pearl. Nevertheless, it is smaller than a 16610 insert for instance (see photo). Quality wise I would 100% say it is gen. Very solid (as all my gen inserts), perfect pearl and nice sheen and numbers. Was there ever a 5513 that used an insert with glass cladded pearl? I did my research but couldn't find an answer. Every help is appreciated Sent from my iPhone using Tapatalk
