Les, I do not know what model that is - I can check next time I am there, if it is still there. Many of those are missing model plates so those would be unknowns. My 505 currently wears a 508 belt lifter.
Yes, that grey lexan goes to crap over the decades. I have a Tradition with a grey fan that looks like a dry Texas riverbed. Needless to say it must be replaced.
I have not started stripping any of those machines, but I did rob some parts from one. I do need to strip some of the worse looking ones as I cannot leave them all stacked on the patio for long.
I may try to restore one Classic and sell it cheap along with the attachments and shampooer set.
I doubt he will give me the gold Heritage - if it does not sell he will take it with him.
I have never seen a full zipper on a genuine Kirby Classic III bag.
I put the two DS50 bag toppers aside for you - see anything else you want or need? A baker's dozen of old vacs maybe?

Ben,
Yes that is what the broke blade sounds like. Vibrates a lot also.
