Kodak Anastigmat 127mm f/6.3.
Kodak Anastigmat 127mm f/6.3 in Diomatic No. 1 shutter. Glass is in great shape for its age, with minor cleaning marks and what looks like a streak of potential glue deterioration. Shutter is fully functional, and includes a neat exposure calculator. Covers 4x5" at infinity, but don't expect a wide range of movements. Outer thread of the mount is approx. 31mm in diameter, with retaining ring and shim.
