It's not a -65…lower right key on a -65 is R/S and it's black. I thought maybe a -67 (of course the guy's thumb covers where the card slot would be) but it doesn't have a light colored upper right corner key (neither does the -65). The only ones that have a light colored upper right corner key are a -35 and a -45, as far as I can tell. I would not have guessed them initially since I'd expect the case to look darker (they are both black), but I'm having to lean toward the -35, as it also looks like there are key legends above he function keys.-kby
