Nein.
But its presence there makes it a lab instrument rather than a
surveying instrument. Also, Google helpfully informs me that
Abelese-Mikroskop means "Reading Microscope".

I'm not so sure that this isn't some homemade device. The body of it
looks strangely similar to a circa 1920 Brass Microscope:

Why wouldn't one Ernst Leitz Wetzlar optical instrument look like
another? The company made a lot of different optical instruments (and
various bits of it, like Leica Camera, still exist).

Sounds like a cathetometer to me. It talks about measuring the precise
attitude of an object, and that seems to mean its elevation angle.
By changing objective lenses, it says you can have objective widths of
5, 9, or 48 cm. I don't know what the mean by the objective width.
It can be precisely adjusted in height from 34 to 55 cm.

1609: Vaccuum gauge, but for what I don't know.
1610: Super dee-lux dowsing rod
1611: The thing in the middle is a roller bearing; I don't know what
the assembly is for.
1612: ???
1613: Kind of looks like an old tube tester, but I've never seen a
portable one nor one quite so substantial.
1614: A surveyor's level. You'd set it so the spirit level showed it
was level all around. Then you'd aim at at some known point (e.g. a
benchmark upon which your woefully underpaid apprentice is holding a
level rod). Then you'd turn it so it was aimed above the point you
wanted to transfer the elevation to, and have someone else hold up the
level rod so the level is aimed directly at it.
I don't know what the numbers are for; typically a level has
crosshairs.

Ablesen means to "read off" (perhaps to "tell by looking")-- probably
refers to the microscope having a calibrated scale.

1609 - It would be really, really nice to have an enlarged view of this,
so as to make out the markings engraved on the front glass. I'm
guessing these may give the item away, since an enlargement is missing.
Anyhow, it seems to be an indicating device of some sort. I'm guessing,
for no particularly good reason, that it has a nautical application,
possibly in ascertaining distance of a log line or something similar.
1610 - Seems to be a tool for levering something a short distance, but
with great force. Maybe it's railroad related, such as to manually move
the points of a switch that is otherwise uncooperative.
1611 - This looks to be a roller (maybe timken?) bearing of hefty size
with the rods welded on. It could form the hub of some small amusement
ride. It could also be a part of a turntable for, say, a large
television set, but the bearing looks designed for radial loads more
than thrust loads, which is opposite of what a TV turntable would
encounter.
1612 - Probably a gauge to measure the width of some relatively thin
things, measured on what appears to be a logarithmic scale (a linear
increase in dimension leading to an exponential increase in gauge
number). The chain is to keep it handy at...well, whatever it's used
at. So, what's measured? No real ideas, although I'll take a stab and
guess small metal extrusions of some sort--channels or I-beams or some
such.
1613 - Self-service tiki torch check. ("Please check all tiki torches
at the door. Thank you.")
1614 - My guess is that it's to measure windage due to gyroscopic
effects for a rifled gun. My guess is probably not correct, though.
It's a tough set. Now to see other people's thoughts.

Thanks, that's a good link, I'll probably use it on the answer page,
although I don't think this Boyce Moto-Meter was for a specific type of car.

I thought that 1614 was a surveyor's level but now I'm thinking you might be
right about it being a cathetometer, I'll send an email to the owner and see
what he has to say.

Near as I can tell most of the text is just description with nothing about
purpose. "Ablese-mikroskop" is apparently commonplace German usage but it's
not in my regular dictionary and I don't know where my technical German
dictionary is hiding.

Another great link, thanks! As someone requested, on the answer page I
added a link to a close-up of the radiator cap, unfortunately the lighting
was dim so the resolution is not good. The rest of the answers can be seen

O.K. Posting from Rec.crafts.metalworking as always.
1609) An ancient radiator cap with a built-in thermometer designed to
stick up above the hood.
1610) Looks like the kind of lever used to lock the doors on the back
of a tractor-trailer, or perhaps the sliding doors on a railroad
car.
1611) Timken style tapered roller bearing -- inner race, cage and
rollers. The rollers look somewhat galled, so I would not
attempt to re-use this for anything critical.
1612) Looks like some sort of cheap screwdriver plus a measuring
gauge of some sort. I at first thought that the numbers
corresponded to mm -- but the step sizes are not right for that,
so it is some other non-linear measurement system.
Not sure why it has the bead chain as part of it.
1613) Well -- it *could* be an over-engineered cart for carrying
golf clubs in numbered compartments.
Or it *could* be filled with liquid nitrogen, and used for
storing sperm samples or something of the sort.
1614) Height? Does it normally sit on the ground as is
illustrated here, or work on a tabletop? The leveling screws
suggest the latter.
At a guess -- it is intended to sweep out a constant height
(used with an upright resting on the ground with measurements
and a target), and the scale might be for approximating the
distance by measuring the apparent angular width of the target.
So it is probably an early surveying instrument.
Now to see what others have suggested.
Enjoy,
DoN.
