Shiloh
Isn't that the very expensive one - something around a grand? I've only heard of them, never seen one. Mine is the Pietta. I would think you would have to find the manufacturer, if they are still making them, and ask them who their agent in the US is. I'm not sure they still have one, or if they are still being made.
Another option might be to write one of the gun magazines, they typically have resources to find these things. You might be looking for a rare bird on the used market.
