I think you did OK.
The newer scopes have a lot better glass than the older ones.
I remember the Weaver MicroTrac, which had a good rep for repeatable adjustments.
But, compare the glass in that 30 yr old scope with your VX-1 and you'll be amazed.
Even a cheap Chinese scope is a lot brighter than those old Weavers.
We thought they were pretty good back in the day.
