I don't believe any US made Weavers were gas filled and sealed, on the older ones you can unscrew the eyepiece right of. They just have O Rings.

I tried Oxpho on an old Kahles I have, did the whole heat and rub with 4x routine. Looked great when I was done. # months later it had faded and turned greenish.

My problem lies in reconciling my gross habits with my net income.
