Can't speak from experience with weather conditions in upstate New York, but I have taken lots of deer here in Texas over several decades with vintage sporting bolt-action rifles wearing period scopes from the 1950s to early 1960s. Lyman All Americans and an Alaskan, Weavers, and Leupolds, some with interesting reticules. I've not been frustrated with light-gathering capabilities and have had no fogging issues. All have given perfect satisfaction. Some came on the rifles as acquired. Some I deliberately mounted for period-correct fun.
Here's the Winchester Model 70 tribe. Three Pre-64s: a '37 vintage .220 Swift, '47 vintage .257 Roberts, '53 vintage .30-06 with a 1980s Super Express .375 H&H Magnum.
