you may be almost right.
substitute 'plane table' for table and you may have it.
plane tabling dates from before the 1950's. the mapping surveyor went
to a spot and put up his plane table and levelled it. then put the
piece of paper on it positioned so that the point on the emerging
drawing was plumbed over the spot on the ground. the sheet was
oriented precisely to the detail and radial lines drawn to prominent
objects. by moving around to other points and plotting to prominent
objects the entire detail could be developed on the map.
you would only need a needle with a small movement to aid in
orientation of the map.
I've never actually seen one so I'm guessing and the technique
predates my surveying time.
a land surveyor's plain tabling compass is my guess.
I think this is right. It is called a "Trough Compass" and
is indeed used with a Plane Table. See the following links
for some examples:
I'm going with the dental press answer for now since there were similar
devices on the link, but I'm open to the idea of an ointment press if anyone
can provide a link to a similar one.
According to the "Dictionary of American Hand Tools":
"The cork cutter was used in drug stores and similar establishments to make
I'm sure they could also have been used to make holes in corks for tubing,
though he doesn't mention that in the book.
I have no idea what an 'ointment press' is. I figured ointment (such as
lip balms, etc) were poured into their containers as liquids and
allowed to cool, not compressed into them.
Knowing that Stellon was a dental equipment factory, I think the
crucible-type thing on EBay was the container where you mixed up the
acrylic before you poured it into the mold. I have no basis for this
(yet, but I'm looking), but I suppose that the central metal cylinder
in the press could have served two purposes: first it was stored in the
press as a 'spacer' to hold the whole thing tightly together between
uses. Then, the dentist or technician would place the cylinder beside
the press, place the cruciable on the cylinder (maybe over a burner?)
while they mixed the acrylic, and then pour it in the mold which was
placed in the press until it cured.
Like I said, this is just supposition. Any dentists here, or dental
Corks to fit in a bottle have a taper (except for wine corks,
which are compressed through a necking device for the purpose of
obtaining a snug fit). Anything produced by these would be straight
(or of that fails due to wrapping, connect to:
and use the search entry to look for "cork borer"
In particular, the description for one of those offered reads:
=====================================================================Cork Borers; Will bore holes in corks and rubber stoppers; Plated
tubing; Smooth plastic handles; Handles stamped with number designation;
Set of 3 ranging 4.8 to 7.8mm
And there are other sets going up to "Set of 15", all of whose
descriptions are identical other than that.
Aside from the vendor being more likely to know the use than a
dictionary writer, consider the term "borer", which is an object to make
a hole in something -- not to make what came out of the hole.

It looks like a chain hook. Not uncommon, except for the flattened part
at the top. It seems like it 'buttonholed' into a link on the chain,
rather than the more common method of using a U-bolt to attach it.
