Gas in Glass from the Past

[Eidetical]

Sixty years ago this month Spectra-Physics introduced their model 115 Helium-Neon RF-excited gas laser as seen below. The ad also below mentions their separation from Perkin-Elmer, as agreed after delivery of the first 75 commercial gas lasers (made by the partnership). This is the laser model used to align the Stanford Linear Accelerator, the BART tunnel under the San Francisco bay, and many other initial applications of the laser.

I've got several glass laser tubes. Mostly Argon and HeNe. But nothing quite as old as this.
