After I posted this, I went looking at panels, just to see what's out there. I think Dunhill has more panels
as a percent of their offerings than any other pipe maker. Others seem to offer them as an unusual shape.
But with Dunhill, it is one of their old standards. I don't shop for Dunhills even as estate pipes or on ebay,
but if I encountered one at a surprisingly low price at a yard sale or antique store, I'd feel like I'd won a lottery.
It's a big Dunhill "thing." foggymountain has nine of them! That's some nice smoking.
