3/4 of the way down the article,
In 1984, Lubinski.it had Paddy Larrigan & Co. at K&P make a few super high-grade Book-Case sets to honor Lama featuring a 4S and an XL339 Briar band. In 2010 one of these was available online in Italy. If I remember, it was $800. Too much for me at the time, but I did get these photos. The grain on these pipes is absolutely unreal.
