I've got an old 453 which I loved, but it got placed in a humid basement for
2 years while I was out of the country and hasn't been quite the same since.
It now takes a lot longer to warm up and it slowly shifts even after it's
warmed up. Maybe it eventually stops, I don't know, but I'm thinking it's
time to get a new scope.
Still, had it been cared for better, I think it would have held up quite
well. Before I left the country it was in excellent shape and was well
calibrated. Certainly well calibrated for hobbiest use, at least.
