My former Mother in law has the Revelation that matchs that
Compact. Except for the lid. It has a hole in the lid that
the hose connects to. Not the rasied piece ontop of the lid.
I actually painted it in the 80's and put a brand new motor
in it and new hose. She is 87 and still uses it on occassion.
Has had several Hoover and Eureka uprights in the same time.
The "pig" as they call it just did not do the work on the 501
nylon wall to wall. They used the floor brush before the uprights came along.
Here's hoping I'm remembered when the house gets cleaned out!
Would enjoy having it in my collection due to the org. history.
