Wiz...Viscount were made from 1956 - 1992. Crown Duke were made from 1964 - 1992. So...your pipes were made between those years.
I also confirmed that wire carving ceased at Grabow around the same time that these lines ended.
Thanks Dave, they have become like a habit that i can't kick.I was looking through some of the old Grabow threads and seen some of yours that you have restored, amazing to look at, i am a big fan of your work.

Joeman, thanks so much for posting that link to the factory. I just watched it and was amazed at how many different processes were involved in making a pipe.
I have to say, some of the early processes looked to be mind numbingly boring, especially if one operative has to do that for a whole eight hour shift!
Regards,
Jay.
