Hello! I've been out beating the bush for a pacemaker lensboard that will accomodate my Supermatic No. 2 mounted 127 Ektar. The new boards available are catalogued by holes that accomodate copal shutters. The nifty metal ruler with the sliding clip I bought to measure such holes isn't much help since I don't have a copal shutter to measure, nor do I have a lensboard to measure to see if it will work. As far as I've been told, a copal 0 should fit the Graphex shutter for the Optar 127. Before I order one, I was wondering if anyone on this forum has had first hand experience with fitting a No.2 Supermatic into a Copal 0 hole or are the Graphex and Supermatics different sizes? Thanks!
