THe WBCCI was formed in August 1955
. Up until that point there had been numbers issued to idenify trailers on Caravans. Numbers were issued to all members of the Caravan, that included non-Airstream owners.
After the formation of the Club, the numbers were controlled and were issued by Headquarters (Helen Byam Schwamborn) to Airstream owners only.
For a period of time several numbers were duplicates. As time went by this changed.
THe most unusal number was Andy Anderson's. Andy a dear friend of Wally's had double zero "00". Andy also became an International President. Andy was also on the first Caravan in 1951, where I met Andy and Dell (wife). Andy went on a Cuban Caravan, and was on the 1956
Andy was Danish and was so proud to show us Denmark when the Caravan toured his native land.
Here is a picture of Wally and Andy having fun.
