I don't have father/son pipes in the sense of a set or anything. But a few years ago I had an idea to buy each one of my sons a year pipe and a tin of christmas cheer of the same year. their birth years are 2006,2009,2012. I have tracked down all tins and pipes with the exception of 2009 pipe. But there are a couple out there I have my eye on.
Fritz Becker (Father top pipe) Paulo Becker (Son bottom pipe)
Hiroyuki Tokutomi (Father top pipe) Yuki Tokutomi (Daughter bottom pipe)
Emil Chonowitsch (Father top pipe) Jess Chonowitsch (Son bottom pipe)
There would also be Sixten Ivarsson Father Lars Ivarsson Son and Lars Ivarsson Father Nanna Ivarsson Daughter. I'm doing this to see how many different combinations there are in the pipe world and what some of these pipes look like, thanks.
Slightly off topic but a month or two ago Roger Wallenstein posted a picture of his daughters first pipe. It warmed my heart to see such skill being passed along. It's fairly awesome that pipe making is kept in families so often. Beautiful pipes folks, thanks for sharing.
