Hiya
Got a really nice lensboard today from a guy who custom makes them on ebay. Color closely matches my Korona. It was PERFECT size copal #3 however, I have an aperture pin on the shutter that sticks into the board. I unscrewed it to get the lens nice an flat on the board. Is this okay? There is a spacer of some sort on the rear thread but only works on the back of the board, not the front. Is this the way the whole copal #3 thing works? The spacer in the back of the lensboard?
