Redfield lens cleaning

I've got a 60's era redfield 3x9x ,same model used on the M40 sniper rifle. The inside of the objective lens looks to have some fungus, and I'm trying to get the outer objective ring off but it dosen't want to move. Is there a trick getting it to unscrew?

    The trick is to have several years of experience repairing scopes, & a workbench full of special tools. That's why I send damaged scopes to professionals:

    +1 for good scopes deserve pro help. I'm thinking if you actually have mold growing in the scope I wouldn't be hopeful, however the crazed look a of delaminating lens is often fixable.

    While not directly pertaining to the OP's letter on Redfields, I copied nmyers list of scope repair firms for future reference. I felt perhaps this addition to that list would be helpful to other readers. It regards repairs to the old Lyman scopes and is from their website:
    "Lyman has not manufactured scopes for quite some time. We have sold the last of our parts and fixtures to a company in Ohio, who is currently making repairs to the scopes. We would recommend you contact them directly at: Parsons Scope Service, 2213 Smith Road, PO Box 192, Ross, OH 45061, 513-867-0820 or psscopes@concentric.net"
    Sorry for the thread drift but hope it helps somebody.

    You need the proper fitting sleeve wrench or you'll bugger up the appearance.
    In the Army, our Div. Ordnance unit had a mobile instrument shop that regularly took apart field glasses, scopes, spotting scopes & did watch & other instrument repair.
    Fungus was cleaned off lenses and prisms using ethyl alcohol as it leaves no residue. I don't recall we had nitrogen to reduce fogging.
    By looking through the objective lens you can inspect for fungus on lenses and prisms.
