I've got some nixie boards I have no use for, there's Iskra 122 board with 16 IN-14 tubes among them and others I don't recognize, sold as is.
So in total it is:
34x IN-14
17x RFT Z5730M
+ some symbol RFT nixies
+ boards with sockets for IN-12
+ some K155ID1
Price let's say 290EUR + shipping, EU only. If you're interested, hit me up!
