Years ago when I needed a part for my 612 Panorama I was told that parts were nearly all gone. A contemporary discussion on galerie-photo.info reported that no more parts for Sinar's roll holders were available. I think this means no support from anyone anywhere. But and however, Sinar is still around and their site www.sinar.swiss has a support section and a contact you want might be sinar@macconsult.de Asking is cheap. Ask.
