In a lot I got at an auction some time ago I found an old brass lens that I'm i doubt whether to have repaired (where and how) or not.
The lens is a Goerz Doppel.Anastigmat Serie no 3 with a focal length of 270mm
It has a serial of 53178.
The aperture is stuck and some of the blades are broken.
Apart from that it is in reasonably good condition (one scratch and some internal dust).
Is it worth the trouble and expense of getting it fixed?
Advice is welcome.
