Mounting Tele-Xenar 360mm lens

[Duane Polcou]

Greetings.

Can a Schneider 360mm 5.5 Tele Xenar lens in a barrel be mounted into one of the pre-drilled copal hole sizes? If not, what is the appropriate diameter hole to be custom dirlled? Can't find this info.

Thanks.

If I'm reading Schneider's data correctly, the f/5.5 360mm Tele Xenar mounts in a No. 3 shutter (Copal or Compur).

That information isn't completely obvious to me, but it may provide enough for others to be more clear.

I have a 360mm Tele-Xenar with chrome trim, s/n 5034XXX that came to me in a barrel with a flange with a thread diameter of 60mm. I tried to remount the cells into a Copal #3 shutter and found that they did not fit. Later I found a Compound #3 that fit the lens cells perfectly and mounted using the same flange as my barrel.

Reportedly the mounting hole for a Copal #3 is 64mm which is exactly the size necessary for my flange with its lip. I have had a few of these flanges and they should not be hard to come by. If you have or can find one, (and your Tele-Xenar is similar to mine), then you should be in good shape.

Thank you. That is the information I needed.

If your Tele-Xenar is older, it may be that it was made for a Compound #3 - see my signature line for mounting threads.
