Duofold RF
Well-known
During my time in graduate school, I bought many Leicas, such as Leica Ms from US military surplus auctions. These ranged from unused or like-new to well-used with separated prisms. I was able to restore them to working conditions. While I do own the original black-painted Leica, I prefer the durability and high quality of modern paint. An example is my IIIc, which chrome plating loss is common due to post war poor quality, I restored it including a glossy black repaint, CLA, and replacement of the shutter curtain and beam splitter mirror.
