jkbff,
No, I don't have the machine but I may be interested in some bison parts if you have those. Please let me know what parts you have when the shop owner finds them! Thanks! Also, do you have a Kenmore Powercenter Upright or any commercial kirbys like american lincoln, supervac 180, or comvac or a Kenmore Heavy Duty wide Sweep? If so, please let me know! You can e-mail me if that's easier. My e-mail is in my vacuumland profile.
