A colleague of mine has a couple of Wray lenses in lensboards I've not seen before. Can anyone help as to what these lensboards fit, and perhaps a clue as to what the lenses might have been used for?
The 4" Supar lens looks like an enlarger lens, and has an iris, but the 184mm Lustrar doesn't, so I guess it's a process lens?
Both have bigger threads than the usual M39 on enlargers.
Any help would be appreciated
