Looking for SB-650 nixie tube

[Tsunehiro Doiuchi]

Hello.

I am going to buy SB-650. It has a disfunctional nixie tube.
I want to repair it and need a nixie tube.
The the Heath kit p/n is 411-264, and a generic part
number of National NL1220.
Burroughs B-5859A is also OK.

I need one (if possible, 6 tubes) nixie tube, or info. for the tube.
I am ready to pay shipping cost.

Thanks.
