Puck Naeco is a bit of an anomaly.  As far as I can tell, there’s only one in-cockpit shot of Puck, and it involves him getting blown up.  The problem is that the way the scene is edited, that should be Theron Nett.  For this reason, Naeco gets the “Red 12” designation and is identified as Red Leader’s other wingman.

Puck ranks below Theron Nett due to screen time and name recognition, but many collectors would like to complete the set of Red Squadron.  His helmet seems to have been reused in Rogue One, so, I guess the character was in Rogue One.  So that’s a selling point?  I don’t know.
