This is just an idea that crossed my mind..
I work in military/business aviation industry, specifically in testing lights used in aircraft manufacturing. We keep records of every test procedure of each unit for 10 years in case a customer requests them (i.e the government, or business aircraft manufacturers).
I was thinking, since many of us wonder how good their "copy" of a lens is, why not contact the lens manufacturer and request the calibration/testing data for that copy based on its serial number?
Did anyone try this before?
