Want to Buy WTB Betax 5 shutter parts or non working parts shutter.

Have a great Wollensak Velostigmat 12" f4.5 and I've got the shutter singing beautifully, but there is no face plate. I would need the face plate and the tiny tiny screws that hold it on. Willing to buy a whole shutter if it has that part. Anyone?? Thanks.
