Ok,
So I just bought a Commercial Astragon 250mm f6.3 in a Copal No.3 shutter with a 4x5 B&J Camera as a rear lens cap. Any one use this lens? Is this the same as a Congo? Tessar formula lens?
My original intention was to mount my 16 inch Red Dot Artar into the Copal No. 3 shutter and send the Astragon onto greener pastures. I have a Kodak Commercial Ektar 10" and a Kodak Ektar 190mm, both of these are in Ilex No. 4 shutters. It is my understanding that the Red Dot can be mounted into either the Ilex No. 4 or the Copal No. 3. Is the best plan to use the Copal shutter for the Red Dot instead of the Ilex No. 4? Should I use one of the Ilex shutters and send the Ektar onto greener pastures?
