Mike, Taurus and B-Square made scope mounts for this model up to 2015. Can still find them on e-bay or auction sites for about $200. Otherwise have to have do most affordable option is to get a gunsmith to drill and tap a few holes into the non structural vent rib so you can mount a standard weaver mount base.

Mike, I would see if the folks at Grand Master LLC can help you out at : http://powercustom.com/store/index.php?main_page=product_info&products_id=753

Oh, man. I'm sure you would have to do a bunch of modifications to the receiver and the top of the barrel. If you get that done make sure it's done by a quality person. Because that round is a powerful bullet. I'm no professional but at the same time the way the top of the barrel is vented might have issues with that type of installation but I guess it also depends on the type of scope you want to put there.

I’ve had a revolver similar to this and I wanted a scope. My gunsmith had to take measurements and drill holes into the top. He used 2 piece bases. You should ask a gunsmith.
