I have a pair of Trenchcoats which got damaged years ago. The orbital has snapped right through. Otherwise they are in great condition. I managed to track down a pair with damaged ear stems but otherwise in good condition. My plan is to use the main frame to replace my broken one. Only thing is I'm a bit nervous about removing the ear stems from my pair without breaking something. I know these are really fragile, does anyone have any experience of disassembly on trenchcoats or other similar era Oakleys. Does it require a log of care? Any techniques that will help? I have disassembled plenty of modern Oakleys!
