RARE...BUY NOW! LOL... This listing is for NEW, UNUSED GENERIC Linhof Technika 99X96mm flat lens boards. They are very well made. They fit newer Technikas as well as many 4x5, and smaller, field cameras such as Walker, Wista, and various other lightweight field cameras. People who don't own those cameras also use these as a nice compact lens board for their field cameras and use an adapter to fit their cameras. It allows for more compact packing and storage of lenses and is a good low-cost alternative to pricy OEM lens boards. Made of solid aluminum - not 3D printed.
