Need help with tube ID

[Lewis C. Emerson]

Bob,
Try this.  Put the tubes in your freezer for 30-45 minutes, take them out and look carefully - & blow your breath on them and see if anything shows up.  This sometimes works wonders.

Can anyone ID this tube? There are two of what appears to be the same tube - one by Raytheon and the other by CBS Columbia. I can find NO markings on them.

Thanks,
