Artisan: Bård Hansen (or Baard)
This pipe has NOT been carved by Bård Hansen but by a former Stanwell's employee who made his pipes with a "Tabago Handmade in Denmark" marking during a short period in the 1970th.
Bård Hansen who has his workshop in Bergen (Norway), doesn't use any logo on his own and true TABAGO pipes.

▲ Pipe of the "Talbert Pipe" line, grade "Signature" from 2003 (carved in France).

Notice the "Talbert" French version stamping.

▲ Pipe of the "Ligne Bretagne" line, grade "Collector" from 2005 and thus carved in France.

▲ Trever Talbert's comments on the above pipe markings:
"There was a brief period (Ed. note: about 2006) when I was marking the stem of each "Ligne Bretagne" with a number of liquid metal dots equal to its grade - a grade 2 got 2 dots, etc.  It turned out to be too costly in material and labor and bother, so I stopped it after perhaps six months.  So, there are a few pipes out there with stem logos, but not many."

Artisan: Trever Talbert is an US pipe maker who established in France from late 2002 to 2009.
