Seeking A Newer Fluorescence Chart

I'm having some difficulty with the Fluorescence Chart in my Unitrade catalog provided by Zatka. There seems to be some inconsistencies unless I'm doing something wrong. For instance he has #1627 as the go to example of Peterborough paper in F. But when you go to its entry in the catalog it shows it's normally DF with LF being #1627i. And there's been a few other headscratchers without getting into details.

Is there a better chart online somewhere I can use?

The best Fluorescence Chart I've found is one developed by Peter Harris a number of years ago. It consists of five stamps that were issued only on a single type of paper. Dull ,= 515 Louis Riel; Low = 561 Frontenac; Medium = 558 Pierre Laporte; High = 625 Ice Skate, and HiBrite = 549 7c Centennial coil.

Thanks for your help, I'll give it a try.

tkoops, you should also try to get the editor of Unitrade to look into this. He is a member of this forum under the name of UnitradeEditor.
