AHD is not in bankrupt, the brand has been sold to their former chief developper Bruno André. They have actually a pretty good success in France with their SeaLion board, a lightwind waveboard/SUP. They still make the board in the Tunisia factory which is still the property of the former owners of the brand (and produces mainly seats for commercial planes now).
As #6 said, most of our brands has never been manufacturers. On the actual market, only BIC manufactures its ASA boards I guess.
