A dedicated viewfinder for the Leitz high-speed medium-telephoto Summarex 85 mm f1.5. The Leitz product code is SGOOD, later changed to 12020. It features a parallax correction mechanism, and the distance scale is in feet.
The design, finish, and clarity are all outstanding, as expected from a Leitz viewfinder. Production numbers were relatively low, making it a slightly rare accessory.

There is some loss of black paint around the eyepiece and scuffing on the chrome-plated area toward the objective side. No dings or dents are present.
The glass is clean, offering the crisp, clear view that SGOOD finders are known for. Ready for practical use.
A genuine leather case is included.
