I have three or four El Paso Weavers. Time has passed them by and I do not think they are worth repair. Lens coatings, and fog protection has surpassed them in the last fifty years even in low price scopes. I can remember a lot of frustrating mornings with fogged up lens in my old Weavers. They were good then but not now.
I have two post El Paso Weavers that are fogged proof, and have proven themselves in sub freezing weather.
I have not tried one of these but I would invest money here rather than in an old Weaver.
http://mueller.geecarts.com/products/show.php?id=14011&type=One of my hunting partners keeps threatening to replace his old Weaver 3x9. I believe it dates back to 1970 and he has taken a couple of bucks a year with it. The inside coating is flaking off, but it maintains its accuracy. So the count is 40-50 deer and he has kept it longer than a wife or-- -.
The last El Paso 4x I replaced is still a good scope but I want the flexibility of more magnification on my Marlin 336. I purchased a Burris 2x7-35 FFII. They call it an x7 but it is actually x8 in high power. It is a far superior scope then the old El Paso Weaver. As I stated earlier the improvements in scope technology is noticeable.
