I have a Kirby Vacuum cloth bag that is a mystery to me as to which model it belongs to. I haven't seen the solid-lined gold logo before. It came on an old Vacuette Electric so I know it is not original to that machine. I am thinking it goes to a Model 505 or 508? I believe the Model "C" series had dashed lines going vertically up and down the front of the bag and the Model 509 had dashed red vertical lines in it. What do you guys think?
