cfz's suggestion:
Good idea. I need to get more Compacts --
On this piece, I added a spine (bracket) from a vintaga hair dryer.
For your suggestion, no added spine. I would leave the original dust bag cover, but cut a hole in it for a smaller viewing bubble. These aluminum vacs cut like butter.
...and use yellow paint (smile).
BTW, I have a yellow submarine in my collection made from an old canister vac.
