Did you find filters yet, John? I ran into my ole stash of 77mm glass Tiffens, incl #12 yellow, all in fine shape. You'd just need a step ring and your Stetson cowboy hat for a shade, with the XX's on the hat matched to the filter factor, as usual. If you want them just PM me your address. Free. But you might get a surplus porch cat in the package too!
