Just bought my first FD Body in a while

Why bother? The EF automatically adjusts voltage and works great with 1.5 volt 625A alkalines.... -
Not just trace elements, apparently these are RADIOACTIVE thorium glass element(s) in this lens, just like the concave front element FD 35/2. Unless bleached by UV light the degree of yellow to brown darkening corresponds to degree of radioactivity. SO as an act of kindness I would be willing to take the darker lens into protective custody for a mere $100 USD (g). Seriously be careful. There may be gamma radiation involved.
