I got lucky on Ebay the other night and got a delightfully rare combination. A Voigtlaender Euryscop Series IV #4 14.33 inch F6 lens in a brass Wollensak Studio shutter #2. I'm anxious to complete this lens to usable shape and the shutter is missing parts. Missing the big collar that turns to set the aperture blades and tells you what your settings are, also the black ring that sets against the collar, and the 'OPEN' 'CLOSED' lever and it's screw and washers. Willing to purchase a complete parts shutter, or an entire lens if I have to. Blades are unimportant. Hope someone can help. The Euryscop is wonderfully usable. I could use it as it is, but it sure would be nice to have it complete.
