Sonnar 6cm f1.5 mystery lens Leica screw ultra rare millitary collectible LTM

Sonnar 6cm f1.5 Leica screw mistery lens , millitary ?

A real mistery lens from wartime, nobody knows it's origin who made it and for what camera.

Many fake ones going on net labeled to Carl Zeiss Jena , but if you examine them carefully,  finish is DIY job vs factory made lenses.

This lens also clearly not looking made by Jena in production , but wartime everything was possible especially in ground bombed Germany..

My guess and share with many others this is made from quality optical glass (glass has same bubbles than Biotar 75) by skilled technicians

perhaps for millitary as we see on three ring finish and reversed dof scale.

Focusing, aperture works , smooth. Seems lens was freshly cla'd before I got  it to try it out.

At first glance lenses are nice clear, no deep scratches , no haze or fungus.

If you light throw it and use magnifier you can see some cleaning marks , a few small spots inside less than 1mm and some trace of not proper cleaning. Overall impressive and very rare lens.

I did try it out impressive quality lens, a bit contrast less I doubt if it has any coating. Works perfectly with Leica range finder.

Come with   front and back caps.

!!!TESTED WITH CAMERA OK!!!
