  Greetings Kato-san:

  Best reference to presribed filters is that of Bessell - can't recall 
  the specific reference, although I am sure it will come up in a 
  reference search. Likely late 1980's or 1990's. PASP, AJ.

  I could locate the reference, but I am presently in Sicily at a meeting and don't return 
  until 22 March.

  Ciao, Guy

I have one inline in my CFW-6 color wheel.  I'm not sure where SBIG
got it, but you might call them up.  Also, a few places that might
stock it:

Custom Scientific
50 West Ocotillo Rd.
Phoenix, Arizona 85013
Voice & Fax (602) 241-1668
Internet: customsci@delphi.com

or this one based in the UK I think:

Schott Glaswerke, Mainz, Germany
Tel - 06131-660
Fax - 06131-662060

Also, Software Bisque sells filters.  I don't have the address
handy, but they are on the web.

You might take a look at the practical filter "recipes" (using Schott
glass) and discussion offered in: Michael S. Bessell, "UBVRI Filters for
CCD Photometry" (CCD Astronomy, Fall 1995), pp. 20-23. This references
another article by the same author: M.S. Bessell, "UBVRI Passbands", PASP,
102 (October1990): 1181.
