After Schneider acquired Goerz they produced these lenses for a while. From what I can find they should be the same as the Goerz red dot APO Artar as it is coated (guess single). Coverage is not great by comparison to some 240mm lens but it is a little jewel in a copal 1 shutter. Matching numbers on front and rear elements. Comes with a kood 43.5 to 52mm thread, 2 caps.
Condition is really nice with great optics and a nice sounding shutter from which I have had no trouble.
A very rare lens.
Looking for £325.00 including SD p&p to UK. Can produce piccies if there is any interest.
