This trade catalog I never knew about until now when I just bought it from Arne in Sweden.
In it is a lot of info (despite being in Swedish) , I learned that the Ambassadeur 5000 B model was released along with the plastic sided ABU 3000 and the ABU 1750 and a myriad of other ABU facts.

If you have any others listed above, that are unneeded or doubles in your collection and are available for a reasonable fee, I would be very pleased to hear from you. Particularly any Record rods or Diplomat series, or Safari Fly rod and a Pacific Series boat rod.
