Thank you Tomasz! Indeed, their color is peculiar and hard to capture in a picture (let alone screen color calibration on the viewing end). Those LD8035 tubes (search for LD8035E) do not seem to be readily available, at least not on webpages written in Latin alphabet. But Japanese do: http://iizukakuromaguro. sakura.ne.jp/422_vfd/422_vfd.html . There are more pages and more interesting single-digit VFD tubes over there!
Their current NOS price seems to be between 1 and 2 USD. The buyers' competion is between "us" and calculator collectors :-) I am glad I got it at "total tube value" rather than "collectible value". I will write an email about a calculator with one more interest group in the next days.
