Durst CLS 300 bits.

Any one know where I can find diathemic reflectors and the 6 ¼ x 6 ¼ inch ( 16 cm x 16 cm ) UV and Neutral density filters a Durst CLS 300 ?

This is the color head with half moon windows for the Y,M,C read outs. I know very little about Durst enlargers and I suspect that this is a very early machine, can any one offer an opinion ? Is there a site or chat room where one might learn about these machines ?

Durst Pro USA.com seems to have dropped off the map ?

Regards to all and thanks for all the informative threads.
