Hi! I am from Hungary! Medicor was a company that made medical electronics in our country. They made also a similar battery charger for Soviet /Russian Sokol radios in 70's. As far as I know the original one was transformerless, it was not accepted, so they made one with it and it was so big. Former European unearthed sockets were flat. They are not in use any longer. We have recessed ones with earthening contactors up and down.

European sockets in Poland has an earthing pin instead of the up/down contacts. They use that style in Germany more often.

I had a metal torch exactly like item number one. It used an old style, and now defunct, 3v 'Flashlight' battery. Those batteries were narrower than 'C' cells, and had a cardboard sleeve/shell. Dimensionally, almost that same as 18650, and no doubt it's predecessor. The white cylindrical device, item number 3; We had the UK version of that thing - Did you ever figure it out? - It's actually a nightlight adapter for a child's room. Ours also had a 12v output, but there was also a 6v version. One would use a 2W to 3W car panel light bulb. The other, used 6v radio dial lamp bulbs. These things seemed to appear toward the end of WW2, and were considered to be safer than a a candle, which could get knocked over and cause a fire. At 3W, the light was approximated to that of a standard domestic candle (1cp).

I remember seeing a torch similar to that when I was younger. It also had a read button next to the sliding switch which I guess was for signalling as it turns on the torch when pressed continuously.

In case of yellow flashlight I thought it is shaver w/o cable.

I used to have a similar flashlight to that blue one, but it was a larger version with D cell batteries. Sadly destroyed by dodgy Chinese batteries leaking inside.

Fantastic video about mysterious old devices. 🔦 I got a flashlight very similar to the one at the beginning from a junk shop (in Switzerland). Mine has a glass made of silicate glass, not plastic, it must be quite old. The socket of the lightbulb broke, it was made of white plastic, I suspect it was cellulloid, which decomposed after decades. I made a new socket out of brass and phenolic resin. A type 2R10 battery with 3 volt goes into such a flashlight, you can still order it. Strange that the light bulb in the video is 3.5 volts, manufacturers usually use a light bulb with a lower voltage rating than the battery for flashlights.

That's a clever button cell charger!

Yes i thought the metal torch was nice too :-D, your 18650 fitted it really well, just a simple plastic tube is needed to keep the battery in the center. You are right with the original "C" cells, they would have ruined the inside :-( Some torches had a center position for the switch, so you could flash morse code, although i don't know if anyone found it that usefull lol. The charge up yellow one looked quite odd, im supprised the cells were still alive. What a strange need for a mains to 12v transformer, i can't think of a reason for that. The button cell charger did look very sturdy and insulated, as long as you didnt allow a modern (Stupid) human touch it LOL. Nice little collection :-D

The original cells probably were two Sub-C or 4/5 Sub-C, not real C. The C is too big for this. Or maybe it was some kind of 3V or 4.5V battery that has been discontinued donkeys years ago. I have seen a second torch of the same type and it had 2.5V bulb instead of 3.5V one. Yes, the bigger torches of the same style had morse code feature. My grandfather has few of those. They also come with an extension pipe, to fit more batteries into it. But you have to replace the bulb for a one with higher voltage rating (or blow it). The NiCd cells are probably the only chemistry of batteries that lasts so long. I also wonder about the purpose of the wooden 12V Edison transformer. The contacts in the charger are almost impossible to touch unless you have very small fingers.
