Sorry about this if it seems a stupid question BUT I recently bought a large old magic lantern Petzval (for £20 UKP) and when I got it home I noticed that the front elements are suffering fron really bad balsam breakdown. I'm not blaming the seller, I should have looked harder. The daft question is if I can seperate the two elements at the front of the lens where the problem is, and if I can clean them up, why would they need to be glued together again to get the lens up and running. Why can't they just be put next to each other without the glue? And would it be hard to clean and re-glue the elements.
Sorry again,
Pete.
