Your example is an ATM 65, rather than ATS 65 (the green focus ring and black lens hood identify), so it's one of the magnesium-bodied ones and would probably sell for more than the aluminium ones. They're also quite rare.Hello. Newbie here! My sister-in-law recently passed and she owned the scope mentioned above, with tripod. If I understand the serial number correctly (begins with U79) it's a 2009 scope. Sound right? It has hours and hours and hours of use. Probably more hours that I could ever imagine. Is there any value in in this "old" gal?
