Some nixie oddities for sale

[Tomasz Kowalczyk]

Hi, 
I've decided to post it here instead of eBay, because here I will reach the passionate collectors (i.e., tube hoarders) of rare nixies. As a tube hoarder I've collected few odd tubes over the years, but I am no photographer and never did anything with them apart from testing, so they are up to trade.
The tubes are mostly Polish early nixies. 

Here are the tubes I own and I am willing to sell:

- Dolam LC-2 tubes - those are different from PIE tubes you can find on Jens or Adams sites, Dolam produced them with hexagonal mesh (PIE has square mesh):

    - Two of them have clear glass, their marking is damaged, but I owned another one with good markings to confirm they are LC-2s. Also these tubes can be easily recognized by decimal point being in front of anode mesh - this is the only tube with such decimal point I know,

    - One with red paint - it looks unproffesional and the paint is over the print, suggesting coating was made post-production,
    - One clear glass, but with internal damage - there is gas, but many digits are not connected due to broken wires.

- Dolam LC-7 tubes:

    - Four tubes in very good condition, print is readable, tubes have very poisoning - nothing severe, just fainter areas on digits, I'd say it's normal for non-mercury nixies. The leads are long and were never soldered, suggesting they are NOS.

- Dolam LL-661 tubes - those are symbol tubes matching LC-631s. They display plus, minus and sine wave symbols. What's odd about them that they have different pinout than Z567M, while LC-631s are drop in replacements for Z566Ms:
    - One NOS tube,

    - One used tube, but working fine.
- Dolam LC-531 with LC-7 digit shape, stack and pinout. Those seem to be a transition state between LC-7 and LC-531 or just mistake in production.

    - There are two tubes, but only one has print on it and the other one has gas. I count them as inseparable pair with value of one tube.

- Valvo ZM1003 - interesting symbol tube matching ZM1000. It shows minus, 1, sine wave and a spiral (!):

    - One NIB tube.

Due to rarity of above tubes* there is no set market value, so I'm estimating their worth to be 50 EUR each (except the LC-531 tubes, which would be 50 EUR for both).

*Even here in Poland I haven't traced a single Dolam LC-2 tube for sale (in fact, I found just one set of photos of one piece of equipment using Dolam LC-2s) , the LL-661 tubes were the only ones I found on internet at all, LC-7 tubes were mentioned in just one polish forum and I have never head about LC-531 with different pinout before getting those two tubes along some normal LC-531s.

Photos of those tubes are in my google drive, link below:

LC-7 tubes are not photographed here, because I've already posted photos of it in Neonixie-l group previously:

https://groups.google.com/forum/#!topic/neonixie-l/XHL9G5VNNsk

LC-531s are also photographed in that thread, in last post.

Best regards and sorry for posting a trade offer in the group - I know they aren't generally well received, but I really think this isn't your everyday IN-12/14/18 sale.

Wrong link to the drive folder... I've shared just one photo instead of whole album.
This one should work.

I wish I could edit the post... Another embarrassing mistake. I've meant Jens and Aleksanders sites.

I know who Jens is but who is Aleksander? I'll take all the info I can get.

Aleksander Zawada was one of the first to build Nixie tubes at home!
Check out his website here: http://www.pwl.mikrokontroler.pl/index_e.htm
