Danbark pipes are NOT seconds. It's merely another brand name Refbjerg uses. The quality of those pipes are the same as the Refbjerg branded ones.
Refering to the Danbark pipes seen (in Europe!) throughout the 70s and 80s they were for sure seconds derivated from the Søren production.
"NOT seconds" obviously seems to be correct considering today's Danbarks. (Even though I've never seen a rusticated Refbjerg.) Danbark trademark only used for USA sales?
