If you have a Sinar with the Sinar shutter you could use it: from back to front:

rear standard <> bellows <> Sinar shutter <> front standard <> this lens

These lenses were designed for the close range but can be used for portraits on 4x5 inch among things.
You would have to experiment a bit with it: mount it on a 8x10 camera with a slow film and use a "hat" shutter.
For experiments it does not have to be fancy.

It is a good lens, so worth it.
