I had seen the Schneider 55mm PCS in Bronica E mount at swap meets, offered by one guy for a number of years, at the asking price of $5500 back in the early 90's.
I had always wondered what appeal for a relatively small AOV of 55mm, considering the availability of 24mm shift lens from Olympus, 28mm shift from Nikon; While wider AOV than 35mm shift lenses from both Nikon and Canon, it didn't seen to provide the coverage for architectural work that could be had with a lot less expense with Olympus or Nikon!
It was far cheaper for me to buy a large format rig than spend $5500 for a used lens for my ETRSi.
