A nicely realized cast and painted metal housing, made by LOMO during the late 1980s, specifically made for the Lomo LC-A and LC-M compact cameras, and good for depths of up to 10 meters.
This enclosure features a small round window on the top to look at the exposure number, a red lever on the front to operate the shutter, a winding knob on the bottom that fits into the LOMO motor-wind fitting on the bottom of the camera, and a small round window at the back to look through the window of the camera's viewfinder.
In addition, this housing comes with a large red plastic plastic viewfinder that fits into the accessory shoe, loosely, and so is often missing or broken, but is useful for framing the composition when wearing a diving face-mask underwater.
These housings were made from about 1988 to 1991, in fairly small quanities.
