Optic lighting cable 'SA'
A very nice original WWII German lighting cable as used with a variety of optical instruments, including the MG34/42 MGZ, 10x80 Flakfernrohr and SF14 periscopes etc.
This particular example remains in superb original condition. It clearly fell into Finnish hands after the war, with the bulb holder displaying the typical 'SA' marking.
As shown, the cable has also been tested and is working perfectly!
