Hi Insky and welcome to the group :D

I can't find a reference on the Lumicon site to a "Type A" filter. I suspect that it's a UHC filter but if you have a link to where you've found this we might be able to tell you more. As BrantUK says if you post this in equipment help as you'll get many more replies. :)

Welcome aboard!

Mark
