Hello all,

Does anyone has any datasheets for any of the Hivac nixies?Looks like there is nothing to be found on the internet .

Also , does any one has any of the following tubes or has information about what they display (in case they exist?): XN4 , XN7 ,XN8 ,XN9 , XN14, XN18 , XN20 , XN21, XN22, XN24, XN25 , XN26

Thank you

Got some of Hivac XN1 and XN3 tubes, these photos were taken about 10 years ago.
Very special nixie tubes.

Datasheets for XN1 and XN12 here:

Yan, 
I know your nice museum and Dieter 's 
Unfortunately there is no Hivac official documentation.
And , moreover , IIRC  XN1 from Lorenz looks different than the Hivac one, will check my stash later .
Hivac was really a manufacturer?

They are mentioned on the last page here but there are no separate datasheets here, maybe they are missing from this document: https://frank.pocnet.net/other/Hivac/Hivac_ElectroOpticalProducts_1971.pdf

Thanks Martin ,
Lets hope that someone could share those missing documents 
I have the following tubes and I could confirm the following info:
GR71M  displays  : mS,S,Hz, MHz,nS,uS,kHz
XNS6839 displays :1/2

some mistakes here :
Looks like the Lorenz and Hivac XN 1 are perfect twins , so the manufacturer is identical for both one , looks like Hivac
XNS 6839 is actually  "XNS " only and I don't see any other symbol , 6839 is only a manufacturing code , if some one has this tube with the mentioned symbol , I will be glad to confirm the model
