Mysterious Object

Hey all, this was shipped to me along with Zenit E olympic camera I've bought from someone, I have no idea what it is... can someone help?

Sorry for the blurry photos, could not find the tripod plate....

I see a case for mobilphone, but the tube seems to have no lenses
if having, could be a camera ocular extender or a part of a hand made microscope? It has caracteristics of being a home made part
It seems to have two dents in the smaller border.

The tube does have 2 lenses, it came in this case, which has some kind of wrench attached to the outside with a snap button. It is too small to be a lens extender, it came with Zenit E and has a diameter of maybe 2cm...

Acording to photos, these lenses have a very small enlarging power.
Did you try to see through it putting it over the camera ocular?
Perhaps a more confortable observer point of view when using camara on reproduction work.

I'll give it a try.. maybe it's some kind of film viewer? The magnification is very insignificant.
