The canister was already a tight fit, so why did it need the little screw to hold it in place?
It took my son's much younger eyes and a good magnifying glass to make out what was stamped on the bottom. APPL'D FOR; it probably said PATENT on the other side. Darn, I was hoping for a manufacturers name.
I think I'll use it as a bud vase.
I'm thinking a candle would be another mighty fine option.
The glass tube was a loose fit, so I tightened the screw just enough to hold it in place.
