Hi... as the title says, I need at least 4 and up to 10 of the itty-bitty Century Graphic metal lens panels. Please PM or email (click my moniker) with offers.
IF the Century Graphic is anything like the Speed Graphic you can cut them out of 1/16 or so aluminum with a jigsaw. If you need more thickness use heat-sink epoxy or some other glue that works on aluminum and attach some stiff foam to the back.
