Thank you for viewing. For sale: LEICA Double Release, Black, [Tested and Working]. There are scratches and marks on the exterior. Please refer to the photos for the detailed condition. I have confirmed that the pin operates when the release button is pressed, and that the release lock can be engaged by turning the knob. #okcamera_productlist #okcamera_Leica I also have other cameras and lenses for sale. We offer discounts for bulk purchases, so please feel free to inquire.
