For Sale FS: Ilex #3 Universal Oscillo shutter

removed from an oscilloscope lens to mount a small dagor(well, that was the intention), then I realized it didn't have any rear threads(for a retaining ring/jam nut)

Will need a CLA, feels pretty rough, but opens and closes.

$40 shipped in the USA

PAYPAL GIFT, PMO, Personal check, or cash are happily accepted as payment

thanks
