PM sent . if you want my info . And if really, important for a positive ID, and you think there one of possible Leopold Run of cap .
You live in Nashville area, but I only live 25-minutes from Leupold and could just drive it over and physically show cap and ask a Tech. in person if it was one of there Cap runs . just pop it in a small 2-3 day Del. flat rate box . and then I just mail it back .
.
edit add.
Your Cap is odd and 1" not that practical for working with these days, everyone want 30 or 34mm . Might be just one of a few caps made/ aftermarket copy retail . Or, I would imagine when the pvs-9 was 1st introduced, there could be all sort of Cap revision done and floating around out there, along with the Runs that were actually submitted for Mil. contract .
