Century Grand Lens Cleaning

[imarabarnett]

Greetings all,

I have a century grand camera that has a lens that needs to be cleaned. However it looks like the dirt is on the inside of the lens and not easily accessible. Does anyone have an idea of how I can clean this lens? Thanks in advance.

"the dirt is on the inside of the lens" - but this could be inside the lens!
There are certainly signs of edge degradation of the balsam.
The front lens comes out of the shutter as a complete cell. Ordinary anti-clockwise release thread. You may need (should) remove the lens board from the front standard before attempting this. You can hold the rear cell and turn the front cell. You have a 50% chance that the front cell loosens before the rear cell. Otherwise the pneumatic cylinders should provide some leverage (careful!).
