You would probably need to find a shutter which originally mounted that particular lens, unless you know the correct spacing you'll be guessing. Shutters of that era were far less standardised than today; for instance I have two pre WWII lenses mounted in the same size Compound shutters, both the threads and the tube lengths are different. Perhaps you can find and measure the shutter of an identical lens to get the dimensions you need. As I pointed out, spacing is critical - just because the cells screw in does not mean they are correctly spaced.
