Well, from my conversations with Richard, you certainly identified the problem, smart aleck or no.A love of flare?

Yes, flare is the problem.
But the reason film holders were sold clear coated is because many users of ULF cameras prefer the beauty of wood grain to a flat black color, and this preference goes back to the very early days of cameras and film holders. If choice were only about practicality the market for ULF cameras and holders would be much smaller than it is.
Most people solve the problem of flare like Michael, they coat all of the internal parts of the holder with a flat black paint. If you find it necessary to paint the outside of the film holder to avoid flare, my experience is that you probably have some type of fit issue that prevents the holder from seating firmly in the back.

To your point Sandy, I send a slew of my 8x20 holders and my camera back to Richard Ritter to properly align them all to fit correctly in the camera. Finally I had to admit that ignoring this issue would not make the problem to go away. Richard did a fabulous job as always.
Some admire wood finish more than utility. My brother was an intense woodworker until he...
I bought RR holders that are efficiently matt black.
I ended up painting all of the interior surfaces of my 8x20 and 11x14 wooden ULF holders a matt black and life for me as a ULF photographer improved substantively. As the old saying goes, necessity is the mother of invention.
As a telescope maker, I can sure attest to the effect of matte black on reflection reduction and contrast enhancement! I'm in the beginning stages of making my own holders, and will definitely paint the surfaces that will be in the light path from the lens to the film.
On my Phillips 7x17 camera with Lotus film holder inserted the amount of cherry wood exposed when looking thru the lens opening is negligible.
Which ones are and why do you ask?
