Yes, that whole series—Heritage 1HD, Heritage II, Heritage II Legend, Legend II—are my favorite Kirbys. I'm not a big fan of dump bags, as I've ranted here before, and thus have converted both of my dump bag machines—my Heritage 1HD and Classic III—with HII parts. The Classic III got a Legend II bag to go better with the color scheme, and the 1HD got a correct orange bag with an HII mini emtor and fill tube assembly.
I love how easily parts from one model often can be fitted to another and work like they were meant to be together.
