Updated photos to show model # and serial # as requested. These are the original HD-B model, purchased in 2014. I've personally ranged 2000yds+ w/ these and the glass is immaculate.
I believe it's the same glass as the Ultravid HD, the Noctivids were released the year after I bought these. I'm pretty sure the current Geovids have the same glass as the Noctivids.
