I found a couple more Savinelli Gold pipes that Smokingpipes.com sold a few years ago in other shapes, but it didn't yield much more information. They're all sandblasts in that same stain, but the gold bands vary quite a bit in shape.
The old Nonpareils with the horn mount also had two gold dots on the stem. I'd forgotten about those earlier. I'll see what else I can find out and if I turn up anything interesting, I'll post again.
