I have a thread going on the repair and restoration of a Durst L1840 10x10 enlarger that I recovered from a screen printing establishment. In case anyone is interested.
The enlarger came to me with a coldlight head and I re-mounted it to improve its performance for fine-art printing.
I'm currently trying Roscoe gels in green and blue for split contrast printing. Seems to be working out very well.
