Mystery Schneider Lens?

Mystery Schneider lens

 

 

I have come across a lens that I cannot for sure identify what it fits.

 

 

Here are the specs:

 

Schneider Anastigmat 50mm f/3.5 with an M39 LTM mount. The lens unit is deeply recessed in the housing which is heavy brass. The distance scale is in feet so I am assuming it is for the USA market. The distance scale focuses to just under 2 feet. The Flange focus is appx 47mm. While it will mount on my Canon P body the focus is way off. I next used a M39 to M42 thread adapter to mount it on my Spotmatic body, it still would not focus to infinity when the lens focus mark was set at infinity. I could achieve infinity by cranking the focus out a bit. The image is rather soft even stopped down to f/11

 

I believe it might fit the Braun Paxette but it looks completely different from the ones listed on the auction site.

 

Had anyone here seen this lens on a camera?

 

 

 

 

 

Maybe someone disassembled the lens and put the elements back in the wrong order/position? It should be a simple triplet or Tessar formula.

It is a triplet, I was able to remove the components and inspect them, the rear is a sealed single lens, the front unit's second element is also sealed, the front most element was in correctly. Thanks for your reply.

probably mid-1951 from Schneider s/n charts

The helicoil could be out one thread and the focus ring was adjusted so that infinity lines up.
