I don't think anyone has commented on the availability of EIR in 120, converted from the 9.5" aerial format.

If anybody deserves some sort of photographic medal it's this guy.

When you refer to a #12 filter, it's a Wratten reference number and is just a bit deeper than a #11 which is your "standard" K2. There's a great deal of information on the filters under Kodak Wratten on Google
I believe coirehogan refers to CC50Y when talking about CC filters.
