Very good camera, but it most definitely "home made".
Viewfinder still has unneeded shatter,
Viewfinder usually has different lens then shatter,
Shatters are different on right and left,
I can not find mechanics to cock both shatters together.
I can not find mechanics to set aperture and speed on both shatters at the same time.
The only what seems to work for all 3 lenses is focus ring.
Writings on the middle ring taken from one more lens.
All screws are not up to experimental cameras, or space camera, as it was mentioned earlier.
Never the less camera seems to be very well made. Great to have in collection for price below 1/10 of the advertised
