Old Spectra-Physics Stabilite He-Ne

[Eidetic]

Here's a really rare AND cute little laser recently found. It's a c1967 Spectra-Physics model 122 Stabilite he-ne system with a model 253-122 power supply. I get the date from a stamp on the top of a component inside the power supply, and the very early "beam directing" features on the head. The resonator is the same design as the 124 (and later 107), but this one's much shorter. Sam Goldwasser has a write-up of the one he has.
