Not an option unfortunately. The brush was ruined before I opened the lens. As it appears to be made out of unobtainium, that will stop most repair shops right there. I can probably manufacture a brush out of a stiff wire, (the Nichrome wire used for old Estes rocket igniters seems to be a good thickness and about the right stiffness, though the resistance is probably much too high, but it's a starting point). I really need suggestions for getting the initial screws out of the lens mount without ruining them..
