This is a really great, informative thread. I'm a big fan of the Jupiter-3. Mine has always focused correctly, as far as I can tell, and the glass is perfect. Reading this thread, I've learned that it is also from the ZOMZ plant, but has the pre 1962 "three lenses glued" logo. serial number is 6109000 -- I love nice round serial numbers 🙂
