Indeed it did, and that bag IS bojack! Bison never made a machine which used disposeable bags. When the Bison factory closed in 1983, Kirby had only started using paper bags 4 years prior. Bison's "sani emtor" emptied from the side, whereas Kirby's from the bottom. Everything about the machine was modified just enough to avoid patent infringement. Some things about the Bison were made very well, other things VERY flimsy.
