Anyone ever have experience with this gun?

What was the relationship with White. They clearly have something in common as the build and marking look the same and in a .504?

Thanks,

the Rio grande was made by Ft Worth fire arms .If i remember it is similar to the whitetail. My understanding is that The company Ft Worth firearms was started up by an ex White employee. I cant verify that though.
here are a couple photos from TDWB site posted by underclocked. I think this one is the one that was on vaguntrader last summer. I've seen a couple in the past year on different auction sites.
