size of a Copal 'O' shutter

[dileep prakash]

Would anyone be able to give me the precise size in mm of a Copal 'O' shutter. I need to cut a lensboard to that size but I dont have the shutter with me. Thanks Dileep

Dileep,

My Copal 'O' through bore is 35mm, with a 54mm backbore for the retaining ring.

You'll find the diameters on: http://www.s kgrimes.com/lensmount/shutmt/index.htm (http://www.skgrimes.com/lensmount/shutmt/index.htm) It says 34.7 mm for the Copal 0 shutter.
