WTB: Schneider 25mm f1.4 Arri Mt. Internal Focus Lens

[Tim Carroll]

I am trying to find a Schneider 25mm f1.4 lens with ARRI mount and internal focusing. These were the later model lenses made for the Arriflex 16S, ST, and S/B cameras. They are different from the more common Schneider 25mm which focuses by the whole barrel of the lens mount turning. Here is a picture of what the back of the lens would look like if it is the internal focus version:

 

 

If anyone knows of one of these for sale, I would appreciate hearing from them.

 

Thanks,
