O.K. The images are confused a bit by whatever was in the
background. So I have some questions:
1) Is there a hole through the stems.
2) Do the tops come off? It looks like it might be a ground-glass
stopper fit with silicone vacuum grease making it appear to be
a single piece.
3) Is the bottom rim a ground glass surface?
If the answer to all three of these is "yes", than I think that
what you have here is a lab manifold for connecting a single
vacuum source (coming through a cast iron or steel plate) and
connecting it to up to five different objects which need the
vacuum. (If less than five are in use at a time, the caps from
question (2) are left on the unused fittings.
2. I know the answer for this one, someone bought a house that was built in
1950 and this was in the side yard almost under a bush.

A composting pail?
3. Someone has about 17 of these 3' test tube type cylinders, each have a
small hole in them, a rounded bottom and no lip on the top.

The first question is "why are all of these images rotated 90
degrees CCW?
The next question which comes to mind is how round are the
holes?
Also - is the bottom lip ground or just heat smoothed?
If the holes are round, and the bottom lip is ground, these
could be vacuum containers -- though very likely to break, so I would
consider them to be very dangerous in such use. If the holes are too
irregular to accept a rubber stopper, then perhaps it is for
introducing a flame (a lit splinter) into a gas mix in the tubes.
Exactly why is a question to be answered by whoever had them made to
start with.
This vase was in the box with the other tubes, it has a finished bottom and
12 holes on the top

Hmmm ... another rotated image -- and too dark as well.
Perhaps stems of roses come in through the holes to make a halo
of blossoms around the glass?

For cutting some round object to length. Obviously not glass,
as there are no burn marks from contact with hot glass.
Enjoy,
