Here in the U.S.A. printing filters are available from Freestyle. http://www.freestylephoto.biz/sc_pro...t_id=&pid=1792
I would think there would be a place to find them in your country.
As for Schneider Kreuznach lenses, they are some of the finest. The top of the line is Componon, and the Componar is a lower cost. I have both for my Durst 606, a 50mm Componon for 35mm and a 75mm Componar for 6X6. Both are sharp for 16X20 enlargements.
My Rollei has a 75mm Schneider Xenar which, while it may not be as good as the Zeiss version, again makes 16X20 prints with no problem.
Hope you enjoy your 'new' enlarger!
