270 is a lantern slide. Edward Van Altena was a famous maker of lantern slides. It's just the right size and is quite thin. Try googling his name and you will come across some great websites with images of van Altena slides. We have a few old astronomy lantern slides at our observatory.
266 is a real mystery object. It looks home-made to me. Possibly for dipping eggs for Easter-egg dyeing? The loop looks a bit too big for this. Please test and see if it can pick up an egg out of a pan of water.
Correct, what I like about the magic lanterns is that they used a flame for a light source instead of a light bulb, there are some really cool looking photos of some a the bottom of this page:

I don't have any eggs, but I can tell you that the inside dimension is 1
An acorn nut is a nut with a blind hole and a rounded end. It stops the threaded rod poking through as a hazard.
Nuts are made by an automatic capstan lathe. Acorn nuts (turned from solid) are expensive to make this way, because they need to be held one way round for threading, then rotates to turn the acorn. This makes them cost several times what a plain nut does.
This type of cheap acorn nut is pressed from thin sheet. A hole is punched and drawn into a rough funnel, which can be threaded. A "flower" shape is then blanked out and the petals bent together to form the acorn.
This type of nut is commonly seen on cheap metal toys, like kid's bicycles.
And -- if you want to see what the other type looks like, check out the following URL:

This particular one has a 1/2-20 thread, so it is significantly larger than the one shown in the puzzle, as well as higher quality.
It is a quick-and-dirty setup -- just the one image cropped to reasonable size. No text, no description.
FWIW -- this is a pair out of the box which I had to order to obtain one for the handwheel on my Clausing tailstock. It had the thin lock nut, but no acorn nut, which led to it working loose regularly, and to occasionally gouging my wrist. I'll figure out other uses for the rest of the box. :-)
Enjoy, DoN.
P.S. Out of curiosity -- now that you have images, what is the term for them in Norway? And what newsgroup are you following this in? I'm in rec.crafts.metalworking, which explains why I am familiar with the acorn nuts, and why I happen to have some on hand to photograph.
Thanks to you and Andy. What they are called in Norway? Frankly, I don't really know, but I'll check it out. (I really was puzzled because my dictionary told me that an "acorn" should be an "oak nut", so what the h... should a "metal oak nut nut of cheap varity" be? :-))
I can see how that would be rather puzzling. The name is because the rounded end resembles the actual nut, and the hex part for wrenching it tight (vaguely) resembles the cap which is found on the acorn.
Thank you. That suggests a background which probably would not offer you experience with acorn nuts. The woodworkers in the cross-posting list might know the acorn nuts. The antiques people might deal with them if they collect old tools and such.
Well, as nut have several meanings in English, and those translate into different words in Norwegian, not all of them are slang for testicle. "Mutter" is the Norwegian word for "nut" as in "nuts and bolts". "Nøtt" (i.e. "Nott" with a slash through the o) is the word for the edible "nut" as in "hazzle nut" or "oak nut". The latter, "nøtt", are sometimes used as slang for testicle, but not very common. (So many others to use, "familiejuveler" (family jewels), "baller" (balls), and so on.) (OT: My first cousing got married in California a few years ago. The wedding menu was Norwegian fish balls, which is shocking by itself as this is the cheapest dinner varity you can get in Norway. As the wedding guests line up a man said "Huh, huh, I didn't know that fish had balls." Lady in front: "It must be large fish though.")

345. haven't a clue but it's fun to see the pics and try to guess
346. mortiser chisel
347. no clue. looks to me to be a non-functional item, like a neat, fun, sculpture.
348. chuck key
349. LOL. that's neat! never saw that before, didn't know it was possible. :-) electric motor. (those coiled wires on the ends of the battery reminded me of the coil of wire used for the "coin shrinker" process, you've seen that right? i wanted to offer a "joke" response for #349, "a **VERY** low voltage coin shrinker")
350. looks to me to be die cast pot metal or aluminum, i would guess it would be unwise to use as a sling-shot. (a spur? maybe... i think not.) my guess would be some kind of very lightweight "spanner wrench" for some very lightweight application.
hey Rob. thanks for putting up these "what is it" things. they're always fun to try to guess. tickles a part of my brain, fun to participate. i thought you really came up with something fun, interesting and unique when you started doing these "what is it" things.
I must admit I'm scratching my head over how that thing works. Assuming the magnets are N pole up, wouldn't the coil of wire just get it's S pole "stuck" facing down at the magnets. IOW, how does the coil turn without having contacts that change the polarity depending upon orientation?
All that is needed is to interrupt the current. I have already posted two ways that I could see it working. (One depends on the wires serving as the axles being just a bit off center.) The other I'll leave you to find my other articles just posted in this thread.
