Does anyone in this august group know where I can find the actual internal diameters in millimeters or inches of the various Series X filters, e.g., Series VI, Series VII, and so forth? I recently acquired a couple of old TLR's (Graflex and Ciro Flex), and would also like to acquire lens hoods that fit them.

Thanks!
