I am SO envious. I recently had a Dr. Grabow laying around that I hadn't smoked lately. I figured, eh, why not...
I openen up the stem and shank to 5/32nds, then rusticated it. I like it a whole lot more now. It wasn't a nice, old Grabow with a history behind it (I wasn't tarnishing a piece of history, in other words.) It was a modern production pipe, and now it has some character, and smokes better.
Now I got the itch to get a block kit like this...
So, I guess that begs the question - where did your kit come from? I understand there are a plethora of folks able to provide pipe kits like this.
Yours looks great! Best of luck with it.
