Hello, I purchased a Tele Arton 270mm (Linhof selected) on a lensboard recently. At first I presumed it was a Linhof lensboard, not having any knowledge of them. But with a bit of research it would seem its not?
The lens has linhof and technika enagraved on it and is dated from 1957. Its set in a compur 2 shutter, hole size 50mm. The lensboard is 101x101mm square and approx3.5mm deep. There are no markings or Linhof shield on it.
Does anybody know the identity of this lensboard? Is it a Linhof?
