I just returned from Jens Jensen place in Portland and whatever you need for the 138 series, he has or is having remanufactured. He is Durst for 5x7 and larger enlarging equipment. He was a very gracious and excellent host.
This was the end stage of the Per Volquartz initiated LF workshop along the Oregon Coast. We aslo paid a visit to Christopher Burkett's studio earlier that day, another gracious host. What a production he has there. We also got a nice showing of 20 or more of his prints.
