Took me a while to find this and I was planning to use it for a handheld 4x5 setup, but decided to go in a different direction. This is a later version with coatings to help reduce flare. Orginally purchased from CATLabs. Glass is spotless no marks, fungus, scratches etc (maybe some small dust) nothing that would impact photos. Body shows it age but no dings, dents etc (some minor pain loss). A lot smaller and lighter than the 150mm 2.8 and should perfect for a field kit or even a handheld setup. $500 - price includes PayPal and shipping in the US
What an interesting lens. Does this ƒ/3.8 version cover 4x5"? I use a 135mm ƒ/4.5 Xenar, and that one does cover 4x5". It fits in a Synchro-Compur 1 shutter. I really like it. Good luck with the sale.
My understanding is that it was largely used for Press (Media) Cameras who needed the low light capabilities of the 3.8 aperture but didn't want the larger heavier lenses
