1923 eureka #9 special vacuum cleaner

I was looking for a date I'm thinking 1923?
Not sure on the value or rareness, but I can't find any other example on-line other than advertisements.
It is all original and works
needs a cleaning, but not going to invest the time unless I know it is sought after and worth keeping.
I've been storing for over 33 yrs
Wife won't let me keep it in the corner :-/
