For my Durst L1000 I am looking for a filter holder (Taufil) and a Heat glass (Taucalo). It is easy to understand if your L1000 has the filter holder, to know if you have the heat glass - you have to open it up. See pictures.
I have a grey Focomat 1C with filter tray, that I would exchange for an L1000 with these parts. Shipping would be to Europe, or to my gallery in NY. If anyone has either part for sale, please send me a message.
