I have a projector lens that is a Petzval by examining the reflections from a point light source.
If the thing is mounted with new barrel components to preserver the original spacing will the introduction of a shutter change its behaviour.
These creatures were meant to be used wide open. Therefore even a ex Polaroid Copal without a diaphragm would be suitable.
I think the focal length is way too short for full frame on 4x5. Am I bothered?/ Nah, I'd try it anyway!
