I recently acquired a Wollensak Velostigmat Series I (not Ia) 6.3 lens. This lens is triple convertible, but I can’t form a sharp image with the cells alone or in combination.
I suspect someone disassembled the cells at one point and flipped a doublet the wrong way round.
Can anyone with a (functioning) Velostigmat Series I please relate the correct lens arrangement? Is it like this: (( )) | (( ))
Thanks for any help!
