| These were brought back from Wollensak Optical in Rochester, NY. Not a clue as to the original use of this filter. Filter is 50mm diameter with 17mm center hole. The mounting is 49mm diameter and threaded (outside and inside). Bottom is 51mm diameter (ID and threaded) and OD is 60mm. 24mm thick. Box is marked as "15239 BBL Filter" whatever that means. Unused in excellent original condition! |
