2605, really no clue. Maybe a plug for some kind of barrel tap?
2606, what a miserable picture to try and make out any detail. That said,
it's a pacifier for adult bulls.
2607, first thought was a tractor fuel filter. But.... maybe not?
2608, is either a barrel bung plug, or a bung plug puller. Might be a barn
hook, screw it into a hole, and use it to hang your farm tools. With the bat
design, maybe hang your Bat Cape, when you're in between saving truth,
justice, and the Joker?
2609, could be a plub bob.
2610, never seen one of these, and can't imagine a use.

2608. That's a miniature commemorative torture device - one end is
for loping off little heads =3D:O
and the other end is for screwing someone. I believe Congressmen keep
them on their desks as "letter openers".
Its funny, I did not even notice that was a hole. I guess I was thinking it
was some sort of reflection because I was not expecting to see a hole in
that type of apparatus. In any case, the hole does not seem to be perfectly
round, like it was a modification for some specific experiment. I still
think the original purpose was as a liquid trap.
After a little more research I see things like this are more commonly used
as part of a vacuum aspirator to suck up fluids. Some have stopcock drains
which may be what that hole was made for, although it does look a little
large and high for that.

2605) A height adjustable foot for something which is constructed of
rectangular metal tubing. The spurs allow it to slide in, but
prevent it from sliding out.
It looks as though it is designed to be adjusted by a
screwdriver from above (with a short tubing, of course), but it
also looks as though it is missing (both in the photo and in the
drawing) a cylindrical foot bottom -- hard rubber, I suspect. or
it is designed to fit over a cylindrical fitting on a lower
2606) A dipper/ladle for dipping and pouring some hot liquid. Perhaps
a wax or the like, perhaps something else. I don't think that
it is for even low temperature metals, however.
2607) Gaertner makes (or made) optical lab hardware -- lens holders
lathe bed style optical benches, traveling microscopes, etc.
This looks much older -- but it may be designed for measuring
the optical characteristics of a gas or liquid. It is not
totally clear whether the round circle in the near side is an
opening, or is a flat window joined to the glass housing..
The fittings on top look as though they are for allowing a gas
or liquid to flow through, and the knurled nuts allow access to
the inside of the container to perhaps change a smaller
container of the substance under test.
2608) Do the "bat wings" at the top form a plane, or a spiral? Hard to
tell from the single point of view offered.
The screw thread could go into something like soft wax, or into
a plug of lead poured with a cored hole, or into soft wood.
Perhaps it is for adjusting the height or spacing of some
object. The wings at the top are not decorative enough to be
something like a top of a hand-carried flagpole.
2609) Rather large and blunt pointed plumb bob. :-)
Perhaps intended to allow replacing the contents to tune the
period of a pendulum. Might even be big enough to make a
reasonable Focualt pendulum.
2610) Looks like something intended to advacne a wooden pole upwards
as the lever is cycled.
Now to post and see what others have suggested.
