Rollei Rolleiflex Bay I 28.5mm Light Green Hellgrun Filter
This is the Bay 1 light green filter for Xenar and Tessar 3.5 cameras.
It is in good condition with moderate wear. There is a small mark on the front side of the glass but I cannot see it without a flashlight, it will not affect your image quality. Otherwise the glass is clean and scratch free with no haze or fungus. The mount shows light wear.
