I scored a freebie on Wednesday - copy of a book by 'The Children's Press', 1962 First Edition of "The Secret Tunnel" by Charles E. Gibson.
Cover illustration has a sea cave with submarine, so it's going to be smuggling and/or spies!

Before lockdown I noticed a black thing at a car boot. 20 quid and a deal was done. Now stripped of paint and a quick dowse in toilet cleaner, I have a huge brass, possibly a valve from a fire station, the thread suits my other branches, not sure, with a little more cleaning and polishing will look nice, somewhere.  You are correct that it appears to be firefighting valve but I would suspect what you have there is a dry-riser outlet valve, something like this https://images.app.goo.gl/ErC83GxCTPrNkQMcA . I would suspect it would be from a demolition of a multi-storey building (most likely a 60's tower-block). Thanks for that idea, I never even thought of a dry riser, you are probably right. |

https://www.instagram.com/p/CCWG1RaC8W5For the first time in a long time, he was free. I visited a junk shop. catch old things from the village house. Pliers, Steelyard, chapelnik (removable handle for pans). And a 1952 radio station, Carbolite. And an old box covered with postcards.

How many tons? Oddly, I haven't been able to find that spec! it is nicely overbuilt, but it was designed for press-fitting wires into cables, and pressfit the cable-end half-shells around the cable socket. prf mvl |

From an antique vendor at the local farmer's market:   It is a novelty book that fires a paper cap when it is opened. The mechanism is just like a cap gun. The pages are from an old grammar textbook. |

Today's find; this fine state-of-the-art radio:  Cost me 30 bucks. All hand-made; possibly from plans printed in an early radio magazine. That big coil is just the right size to have been made from a cardboard Quaker Oats can. Missing is the ear phone and the galena crystal. Just a reminder that not all early electronics contained vacuum tubes. Do they still broadcast the Arlington Time Signal? |

I think copper oxide or a grapite pen tip on a razorblade tecnically would do, but a crystal would look awsome.
I think for example pyrite will do as well as galena, but maybe does not look that nice. However both are pretty common crystals to find in mines.
With the germanium diod i think any crystal will do as display, anyway.

 I think i will keep this as it is and just clean it up a bit and repair the knob. (i want to keep it functional so it can be used for it's intended purpose). Probably from an old army fieldradio telegraph set. I got this realy sheap on a national internet action site (probably because it was labeled wrong and did not show up in the normal search list), i think it was like 4 cent or so + another 6bucks for the shipping, normaly they are quite expensive here. |

We had a New Year. And Ded Moroz brought the boy Morozov and his daughter a gift. Filmoscope. Soviet hayen filmoscope produced in 1990. A powerful lamp that allows you to watch filmstrips during the day, a control panel on a wire 8 meters long. The ability to view slides and biological preparations (instead of a microscope).  Even Ded Moroz brought a set of filmstrips 60-70-ies dedicated to agriculture in wonderful carbolite boxes.  He brought children's stories, too.  Well, a bonus, one of these filmstrips dedicated to the technology of cooking smoked pork - https://www.instagram.com/p/CJl1G12KxLE/ |

My Dear Morozow - That Is Beautiful! My wife tells me that the oldest color of glass is naturally green, and that a bowl-shaed glass is ideal for brandy  yhs prof marvel It is true that the oldest colour of glass is green - this is because of small quantities of iron present in most sand. You can see this colour if you look at a sheet of window glass edge-on. Glassmakers do their best to get rid of it. But the green colour in this decanter and glasses is a different one, and deliberately introduced. Have you tried looking at it under ultra-violet light? If it fluoresces, then the colour is due to a small quantity of uranium. https://en.wikipedia.org/wiki/Uranium_glass |

What's the symbol on the lids? It looks like a hammer and some other tool. |

Looking at my copies, I would say that a hammer, a jackhammer and a photo tape. But I found another version of this image, maybe it's a caliper. https://diafilmy.su/forum/topic/26-korobochki-dlia-diafilmov/#entry87These filmstrips are made - a Factory of on-screen educational and visual aids. |

not quite, though close. Rather, reviews of some topics for professional development. For example, I gave a link to Instagram, there are frames from filmstrips dedicated to the methods of processing pork, for the manufacture of smoked meat.
There are for example filmstrips about useful and harmful microbes in relation to agriculture.
About caring for the hooves of farm animals.
I can assume that they could serve as illustrative material for lectures and some training courses. I have seen references to pamphlets accompanying such filmstrips.
