Btw..I believe that 889 to be a Optical Comparitor calibration unit. Its
nearly identical to a J&L I saw late last week.

Haven't been able to verify any of the the guesses yet for this device, but
I just listed most of them on the answer page:
- Optical comparator calibration unit
- Measuring device for recon aircraft images
- Used in cartography to check a printed scale
- Coincidence gauge
- Scale for measuring motion of something behind it
And I'm still waiting for a reply to my email to the manufacturer of it.
891: Guess: Lifting wedge. Used to lift septic tank cover. Shove into
round hole in heavy stone or concrete thing. Lower part then rotates and
wedges. Lift cover, clean septic tank.
892: Guess: Nutcracker.
891 - I have no idea, but my first thought was a pendulum for ringing
a bell, despite the movable part.
I thought septic tanks would have bar handles for lifting. Having a
hole in the lid, somehow, doesn't make sense. I am not knwledgeable
of of septic tanks or services, but that answer sounds more reasonable

890 looks like an old window crank
894a & b I'm going to guess they're old maple syrup taps. The red cloth
might be a flag so you can locate it later on.

893 is the fuse that goes into a fuse cutout on an electrical distrubtion
line. It serves a dual purpose. It (obviously) acts line a fuse for an
overcurrent condition. It's also used to "take out" a section of line for
maintenance. The lineman would use his hotstick to grab the loop in the top
to open and close the cutout.
You can see an example of one here

890) This looks like an example of the control crank for casement
windows -- but a bit weaker than the current ones.
891) This looks like a sounding lead. The hole in the back of the
pivoting piece gets stuffed with grease or tallow, and the thing
is oriented so it is down.
When it hits bottom, it picks up samples of the bottom sand,
allowing the pilot to get a better idea just where he is. (As
well as the length of line telling him just how shallow it is.)
When the line starts to be reeled back in, I suspect that this
releases a simple catch and the rounded end turns downward,
moving the sample in the tallow into a protected area.
892) This is for squeezing a cork down to a smaller diameter, so it
can be inserted into a bottle mouth and then expand to fill the
893) This one sort of looks like part of the tooling which the power
company uses to pull and replace fuses in the moderately high
voltage lines feeding the transformers on power poles in
residential neighborhoods. There is a lot more pole past the
pivoting part shown which is missing -- and is probably why it
was not recovered.
894a) A chisel tip for a jackhammer, perhaps? Perhaps the hollow
is to feed nitroglycerine into a split driven in stone by the
chisel. And the ring would be for attaching it to a chain so it
could be recovered after the blast?
894b) Is this one for drilling holes in stone to place dynamite
charges for breaking up the stone? It certainly is driven with
895a) Perhaps a postage scale? Stand the envelopes in the slots
until you find the one where the envelope overbalance the
895b) If the above is right, I really don't know how this one is
