Subject: unknown spectrum tube

Post:

Tappers,

We have 3 spectrum tubes with no marking on them that were separated
from their "bin" before my arrival here. They look old but appear to be
unused. They emit a continuous spectrum except for dark bands at the
yellow-green transition and far red. By comparing them with the online
source at:

they most resemble carbon, or maybe fluorine. Does anyone recognize this
spectrum? Thanks in advance...
