Serial number XX032056 which is 1st Gen I believe. Very good condition, however there is some orbital pitting on the right upper section. Just one of those character flaws from the mothership and hardly noticeable, however it's nothing a refinish by the X Man won't fix if you want it to be flawless. I've had these for 3 years and just noticed myself. Frame is tight with little play in the bridge. FIP Lenses cut from Big Taco donors. Red rubbers from linegear but will include OEM rubber with purchase. I'll also throw in a pair of OEM blue iridium lenses as a means to offset a refinish job or just to have a different colorway. Glasses and bag only. $375 all in if shipped to CONUS. Will ship international but at the buyers additional expense which will vary by destination. Buy my XX and XM/Ruby Juliet and I'll do $700 for both. Thanks for looking!
