Hey there. I have a couple of lenses that may do the trick. I have a 65mm f8 ilex wide-angle lens. it is not labeled as such, but I have another one exactly the same that is labeled. I think i have it in a size 00 prontor-press shutter. The shutter needs to be marked for the aperture. It should cover 4x5 but I can test it out for you if you are interested. I would probably sell it for around $100
I should also have a tominon 127mm lens I can send you on the cheap.
I am not too sure what you are looking for.
