This looks like a Fulton unit, one of the more desirable versions. In April of 1950, KF made an adjustable unit available as a factory accessory at a list price of $17.95. Fulton and other manufacturers made and sold visors in the aftermarket (Western Auto, Sears, etc) as well.
If this does indeed fit a Henry J and all of its parts are present (mount brackets, etc) then it does have value. Most that fit the full size Kaisers tend to sell anywhere in the $350 to $500 range if complete.
I've seen them on ebay and on FB marketplace. I'd search for Fulton sunvisor.
