Many of these earlier Weavers seem to have problems with the cement holding the (erector?) lenses together, rather than a fogging problem per se. Not particularly difficult or expensive to repair but a PITA nevertheless.

Most underestimated scopes in my experience and opinion? Lyman All-Americans and Perma-Centers. Slightly later time period than the rifle in question though.

I like scopes and have owned/used a lot of different brands over the years. The only scopes I actually seek today are vintage Lymans and Unertls since they seem to retain their optical clarity longer than the others.
