I can't tell for sure, but Google says:
- optical scheme is similar to Schneider Tele-Xenar;
- this lens covers up to 24x36cm (maybe even more).

Lens is in excellent condition for its age.
Please look at the pictures carefully, what you see is exactly what you will get.
No damages on glasses; some marks, light scratches, dusts and maybe light haze, which is pretty common for vintage lenses and usually have no influence on images.
I don't have proper camera to check this lens so I sell it AS IS, no returns please.
Any questions - please ask. I'll be happy to help.
