Kodak has discontiued making the 23A filter.
They have substituted the 22 filter wich is virtually
identical in absorbsion characteristics. We use it in
our Lab at Sigma Chemical. I take it you need a
37 mm screw-in glass filter. I would call Kodak
at 1-800-242-2424 to find a source for such a filter.
Sigma Chemica, St. Louis
