I have restored filters on four different EBBCo's with success using solar film and layered post optomitrist exam sunglasses. It is easy to pop the plastic filter retainer ring out then cut to fit the film using the original filter as a template. Pop the plastic ring back in over the solar film and you are good to go with bright sunlight.
