Can you post some images of your lens?
Not sure how to mount yours but in terms of useability I think these lenses should have lots of potential. I have a similar lens, not in shutter, see below. I've only ever used it with a full frame 35mm digital camera (on a Sinar) and the images are quite sharp IMHO and background bokeh seems quite soft so I think this would be a very useful lens with film. I always planned to get a 6x9-6x12RFH for a Sinar and I never quite seem to get around to it. It's on the 'to-do' list.
Mine has a very odd serial number which has not allowed me to date it in any way. I assume you have a normal Schneider serial number, not the short one like on my lens.
See sample images below from FF (35mm) digital camera, ie. a very small central portion of the 4x5 that I think (not sure) this lens covers.
