I have two older model cams, they are both a number 1 size but there are some clear differences, namely the colour and the hole shapes in the lobes. Looking online, I think the 4 digit code on the bottom of the lobe is in the format of YDDD. Cam #2 has a code starting with 4, and also has 2014 on the sling tag. Cam #1 where the code is 5327 however has no year on the sling, so my question is is it from 2015 or 2005? Obviously I will be re-slinging these before use.
