Stone, that's what I was looking for. Every wratten filter I've ever seen says wratten on the ring. I've never seen "Pictorial" on a ring or a box. When my internet search for "Kodak Pictorial Filters" returned zero results, it seemed like this could be a different filter, or, it could be the same animal with a different (and less used) name.

Wratten filter "marketing".

Thanks for the shout!
