In the mid 70's as best I recall I purchased a Weaver T-10 with 5/8 minute dot. I have not used it in many years. I had a need to scope a rifle so I pulled it out of moth balls and mounted it. it is not foggy but dingy. looking into the front of the scope I can see that the glass needs cleaning but all the dingy stuff in inside the glass. I say all this to ask where and who is a trusted somebody to get to clean the scope up.
