Recently acquired this Hoover celebrity IV Elite, looking replaced some damaged and missing. This is probably a long shot but need a replacement upper exention wand (locking rivet gone), lift-off tool organizer, bare floor nozzle and possibly even a matching power nozzle. The vacuum itself is in rather great shape. Completely went through it, cleaned and lubricated. Runs fantastic!
I would check regularly on eBay, can sometimes find loose sets of attachments and wands there, maybe the power nozzle also. Possibly an old vacuum shop in your area might have some parts too. Also thrift stores, but parts of this age I never have luck finding there myself.
