That is an outstanding collection, great job, those are really beautiful pipes. Dr. Grabow, I would have never thought. Many of those wonderful shapes remind me of old Stanwell's, Kriswill's and Dan Pipes.
I would love to know the back story on who carved these for Grabow. I presume that they were not carved by Grabow, but I could be wrong, would not be the first time!
Beautiful collection and end to quest, which is always rewarding!
Enjoy,
Lou
