Want to Buy WTB: Packard Shutter, 5"sq

Hello, I need a 5" sq Packard shutter that is in good condition and functional. Thanks

Cheers!

One time i needed a big shutter so i researched a drop shutter. Then i advanced to making a hand operated 8 inch shutter by rotateing the outter poloroid filter. Research crossed poloroids decreases light transmission. Filters are made in film or very stiff plastic
