I purchased a Kodak Series V filter sold as a "Wratten G Filter". As dark yellow contrast filters (Wratten G) can be hard to come by, I bought it. Turns out it's a macro diopter.

I'm not contesting it with the seller, since the filter ring itself states "Series V Wratten Filter G". However, the lists and catalogues I've found have listed G as either Orange or a synonym for No. 15 Deep Yellow. As far as I can see, series diopters were 6A and 7A. Is this factory-mislabeled, or perhaps a frankenfilter repair job?
