This is a ‘Diana DeLuxe’ clone, which I got for £1.04 on ebay, made of grey plastic.
It has three aperture settings which appear to be around f8, f11, and f16. The shutter speed is stated on the lens to be 1/50 of a second. The lens also has a zone focus system with settings for 6m to infinity, 4-6m, 2-4m, and 1.2-2m. Other than that there is little information on this camera on the internet. Not that there is much more to say, really.
The Diana DeLuxe versions shoot 12 frames to a roll, and have a distinctive curved film plane which minimises aberration from the simple meniscus lens.
