Gosh! I'm not skilled to unpack such pathology, but suspect your psychiatrists are fascinated with you.

Tiffen is creating for us a custom 86mm filter for a cost less than $200. They were very helpful. Much less expensive than we were guessing ahead of time. Their largest manufactured size is 77mm.

Correspondence with B+W was helpful but they do not make a Wratten 2E equivalent. This is their response: "At one time, B+W offered the 420 filter, which approximated the Wratten 2E. Unfortunately, this was discontinued in 2012."

Thanks for the update with the added details. I'm glad they were able to provide what you need.

One quick note of clarification... Tiffen does offer a variety of stock filters much larger than 77 mm, but the Wratten 2E is a non-stock custom order larger than that size. As you discovered, Tiffen is able to provide custom filters for a reasonable cost.
