The article your refer to was in Camera and Darkroom Photography.
Here are a couple of other sources, one in English, one in Swedish.
Alterbernd's article should definitely be of interest:

Project”. Camera and Darkroom, January 1993, pp. 12-16. N. Hollywood,
CA. (Enlarger back for 4 x 5 Bender camera.)
