Cor....that list from typed by Andrew Molitor has been on my homepage for 
several months now....;-))
My 'added value' is a comparison table between Wratten, Schott, B+W and 
Heliopan, all with their respective 0 & 50% transmission marks. 
Think I'll add the two Hoya's to it as well, together with some 
antique Wratten numbers from a 1928 Wratten catalogue.
