Both of these systems can be counted among the various attempts to create a bag compression system based on mechanisms that differed from those patented by other manufacturers. Given the relative complexity and the low technical efficiency, both have not had any significant follow-up. Their rarity, however, makes them interesting from a collector's point of view.
