Like the others have written your grandfather had great taste and it appears there's more of his DNA on the Preben Holm's: that would be the gray, crusty residue on the mouthpieces.
Holm was a masterful Danish carver and he was savvy enough to be in the forefront of the Danish explosion in the U.S. during the 60's. He later bought the great English marque, Ben Wade, and employed as young men, the superb Danish carvers commanding the highest prices today. De mortuis nil nisi bonum aside, Holm drank himself to death and lost his wife and kiddos in the process. Sad story to be sure.
The Benner, Dmcmtk asked about, is just beautiful. Benner was a protege of the great Karl Eric Ottendahl who was, in turn, a protege of Holm so it all gets pretty incestuous with those amazing Dane carvers. Your Jobeys aren't slouches either: that Jobey Dansk was made by Karl Eric as well.
I have one of my grandfather's pipes sitting before me in his favorite ashtray. You have a treasure chest in front of you. We're both fortunate to have those memories. Grab that Savinelli or Dunhill polishing cloth and enjoy them for the works of art that they've always been.
