Things You'll Need
Instructions
Remove the shutter lens and its flange from the camera with the flat-head screwdriver. The flange is located on the front of the lens board, and the shutter lens will come out once the flange does.
Mount the brass lens to the lens board by screwing the lens flange through the lens hole and back into the lens board with the screwdriver.
Test the brass lens' strength and functionality by twisting it with your hand. Tighten the flange, if necessary, with the screwdriver to finish attaching it to your shutter camera.
