These look very much like Chinese types I've seen, I guess the Russians and Chinese were working together on these or traded them.
There are also two dots in the sign tube which makes it possible to show division too as one dot above and one below the minus sign like: ÷. Lately I saw a kind of game with the tube where you were supposed to enter the right number after game had presented numbers and signs in a row - I think it was a Russian game. It worked like the game presenting a few numbers with a combination of plus/minus/multiplication/division between these numbers and then there was an equal sign and a means for the player to enter the answer - 4/2+5*3 = ?? (17). /Martin On Thursday, 16 February 2023 at 20:55:33 UTC+1 Audrey wrote: > Oh no you guys found it haha, I'm really curious what the IN-7 type ones > are, one looks like a fine-grid/prototype IN-7, the other one I've not seen > before, - + × > > On Thu, Feb 16, 2023, 2:48 PM 'bogdan paduraru' via neonixie-l < > neoni...@googlegroups.com> wrote: > >> very nice ones >> >> On Thursday, February 16, 2023 at 09:17:08 PM GMT+2, Nicholas Stock < >> nick...@gmail.com> wrote: >> >> >> >> https://www.ebay.com/itm/Set-of-unknown-nixie-tubes-with-symbols-rare-collection-NEW-OLD-STOCK-/225424006907 >> >> Not my listing of course, but interesting looking for the collectors here! >> >> Cheers, >> >> Nick >> >> -- >> You received this message because you are subscribed to the Google Groups >> "neonixie-l" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to neonixie-l+...@googlegroups.com. >> To view this discussion on the web, visit >> https://groups.google.com/d/msgid/neonixie-l/CAOX%2BRHLNsPgNY2Rpvd6uua5dopHBEQBvovjQUPKmr1xUHkHNCQ%40mail.gmail.com >> >> <https://groups.google.com/d/msgid/neonixie-l/CAOX%2BRHLNsPgNY2Rpvd6uua5dopHBEQBvovjQUPKmr1xUHkHNCQ%40mail.gmail.com?utm_medium=email&utm_source=footer> >> . >> >> -- >> You received this message because you are subscribed to the Google Groups >> "neonixie-l" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to neonixie-l+...@googlegroups.com. >> > To view this discussion on the web, visit >> https://groups.google.com/d/msgid/neonixie-l/840384201.1525126.1676576919565%40mail.yahoo.com >> >> <https://groups.google.com/d/msgid/neonixie-l/840384201.1525126.1676576919565%40mail.yahoo.com?utm_medium=email&utm_source=footer> >> . >> > -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
