Bonjour Frédéric.
You have several options.
You can start from catalogs that offer new Rollei bayonet I filters.
in Europe we have Heliopan and B+W in Germany.
Wratten filters have their equivalent in other brands. What is
important is the transmission curve of the filter. Non-Kodak
manufacturers usually give the Wratten equivalent of their filter.
Kodak has a nice technical publication on Wratten filters with all
curves and possible applications.
The other option is to use an adaptor from bayonet I to a screw-mount
filter. Heliopan has a bayonet I to 30,5 mm adaptor ring but 30,5 is
not that easy to find (exceot for those who use a Rollei 35 Sonnar
routinely ;-) !
SRB film service in the UK has a baypnet I to 46 mm adaptor. 46mm
filters being more "35mm-Japanese" in size ;-) are easier to find.
Useful info :
Kodak Filters for Scientific and Technical Uses, Kodak Technical
Publication No. B-3H (no idea whether this useful publication is still
available !!)
Heliopan : http://www.heliopan.de/picts/Preisliste.pdf
B+W : http://www.schneiderkreuznach.com/pdf_filterkatalog.htm
SRB film service : http://www.srbfilm.co.uk/
